angiofibromas) that are in areas prone to trauma. endobj Focal dermal hypoplasia is a genetic disorder that primarily affects the skin, skeleton, eyes, and face. The symptoms include basal cell cancers, jaw cysts, skin pits on the hands and feet, and abnormal deposits of calcium in the brain. Nevoid basal cell carcinoma syndrome (NBCCS; MIM #109400) is a rare autosomal dominant, tumor-predisposing disorder caused by germline mutations in the human homolog of the patched (PTCH1) gene [ 1 ]. General Discussion. Patients with Clinical Features. The majority of the mothers of females with these X-linked dominant lethal disorders are unaffected, and the variant alleles are therefore thought to arise as new mutations. Goltz syndrome is a rare genetic condition characterized by involvement of the skin, skeletal system, eyes, and face. It appears to involve diminished synthesis and enhanced degradation of collagen.980–982, Epidermal thinning with loss of the rete ridges is an early change. Gorlin and Goltz (1960) described a familial syndrome comprising multiple nevoid basal-cell epitheliomas, jaw cysts, and bifid rib. In some disorders due to mutant alleles of genes on the X chromosome, affected males are never or very rarely seen (e.g., incontinentia pigmenti and Goltz syndrome). In one of these cases, low level signal for the mutation was identified in the girl’s father suggesting somatic mosaicism, but all other parental samples were negative for the mutation, consistent with new mutations in the affected girls. INTRODUCTION. There is asymmetry of the face, trunk, and limbs. Skin manifestations present at birth include thin skin and areas of missing skin; fat nodules in skin manifesting as soft, yellow-pink nodules; and pigmentary changes. The epidermis may be absent or thin, with only two or three layers of flattened cells. Focal dermal hypoplasia is a form of ectodermal dysplasia. The disorder is also associated with shortness of stature and some evidence suggests that it can cause epilepsy. First described in 1960 by Gorlin and Goltz, [4] NBCCS is an autosomal dominant condition that can cause unusual facial appearances and a predisposition for basal-cell carcinoma, a type of skin cancer which rarely spreads to other parts of the body. <> The term ‘pseudoainhum’ refers to congenital constriction bands which may take the form of shallow depressions in the skin or deep constrictions associated with gross deformity or even amputation of a limb or digit.962,963 The term ‘ainhum’ is a West African name for similar constrictive lesions, usually of the fifth toe, that lead eventually to spontaneous amputation and that probably result from the effects of repeated trauma in the genetically predisposed African patients. The skin abnormalities are present from birth and can include streaks of very thin skin (dermal hypoplasia), cutis aplasia, and telangiectases. Goltz syndrome (Goltz, 1992), also known as Focal Dermal Hypoplasia (FDH) is a rare, X-linked developmental disorder characterized by variable presentation of multiple abnormalities that result from defects in development of ectodermal and mesodermal structures. In some disorders due to variant alleles of genes on the X chromosome, affected males are never or very rarely seen (e.g., incontinentia pigmenti and Goltz syndrome). The degree of clinical severity varies widely. All three conditions are regarded as congenital follicular dystrophies with abnormal keratinization of the superficial part of the follicles, and are therefore considered with other follicular abnormalities in Chapter 15, page 433. Summary. Nevoid Basal Cell Carcinoma Syndrome (Gorlin-goltz syndrome): Visual mnemonics/ Gorlin-goltz syndrome simplified Goltz syndrome, also known as focal dermal hypoplasia (FDH), is a rare genodermatosis characterized by widespread meso-ectodermal dysplasia. The majority of the mothers of females with these X-linked dominant lethal disorders are generally unaffected, and the disease alleles are therefore thought to arise as new mutations. Its incidence is 1–3 per 10 000 births.859 The defect is most often limited to the vertex of the scalp,860,861 but other parts of the body such as the trunk or limbs may be affected, often symmetrically, with or without accompanying scalp lesions.862–866 Scalp defects range in size from 0.5 to 3 cm in diameter but larger defects up to 10 cm in diameter have been recorded.867,868 Other recorded associations include limb defects,869–872 mental retardation,873 split cord malformations,874 oculoectodermal dysplasia, encephalocraniocutaneous lipomatosis,875,876 epidermal and organoid nevi,877–879 epidermolysis bullosa,859,880–884 chromosomal abnormalities,863 fetus papyraceus,877,885,886 and focal dermal hypoplasia.863,873,887 The Adams–Oliver syndrome (OMIM 100300) refers to the combination of aplasia cutis congenita and transverse limb defects.888 Other systemic abnormalities, including coarctation of the aorta, may be present.889,890 The gene responsible has not been identified. Gorlin–Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, is a genetic disorder with several neurological, cutaneous and skeletal manifestations. Looking for other associated features is important. The former defect is inherited as an autosomal dominant trait, and the latter as autosomal recessive.1007, There is thinning of the dermis with the collagen bundles arranged parallel to the skin surface.998 Elastic tissue may be normal or reduced in amount. <> The following conditions, discussed below, can be associated with a decrease in dermal thickness: In addition, dermal thinning can be seen in type IV Ehlers–Danlos syndrome (see p. 327) and also in some forms of Marfan's syndrome (see p. 350). This is thought to be due to a lethal effect of the variant allele in the hemizygous male, resulting in nonviability of the conceptus during early embryonic development.

Mutations producing Goltz syndrome have been identified in the porcupine, drosophila, homolog of, (POCN) gene (195). There is occasional mental retardation. Its clinical phenotype varies widely, ranging from isolated skin defects to absence of limbs and/or organs. As a consequence, if an affected female were to have children, one would expect a sex ratio of 2:1, female to male, in the offspring and that one half of the females would be affected, while none of the male offspring would be affected. endobj At the same time, Wang et al. Focal dermal hypoplasia (FDH), also known as Goltz syndrome, is a rare multisystem disorder that principally involves the development of the skin, hands and feet and eyes. There is a marked reduction in the thickness of the dermis, with some thin, loosely arranged collagen fibers in the papillary dermis. Description: Focal dermal hypoplasia, also known as Goltz syndrome or Goltz-Gorlin syndrome, is a multisystem disorder characterized by linear areas of skin atrophy with variable pigmentation, fat herniation, skeletal anomalies, papillomas, digital abnormalities (syndactyly, polydactyly, camptodactyly, ectrodactyly, and absence), nail and tooth abnormalities, ocular anomalies, and sparse hair. Epilepsy has been previously reported as a finding in Gorlin–Goltz syndrome but remains ill-described in the context of this disease. Cutaneous manifestations include widespread areas of dermal thinning in a reticular, cribriform and linear pattern, soft yellowish nodules representing either herniations of subcutaneous fat through an underdeveloped dermis or heterotopic fat (a fat nevus),930,931 and linear or reticular areas of hyper- or hypopigmentation, often following Blaschko's lines.917,932–934 Lentigo-like pigmented macules at the periphery of atrophic lesions have been reported.935 Focal loss of hair, nail changes, total absence of skin from various sites, exophytic granulation tissue,936 apocrine hidrocystomas,927 lichenoid hyperkeratotic papules, giant papillomas,937 and periorificial tag-like lesions may also occur.917,932,938 Skeletal abnormalities include syndactyly, polydactyly, and longitudinal striations of the metaphyseal region of long bones (osteopathia striata).933,939–942 Dermal hypoplasia may be a manifestation of the Proteus syndrome.943 Rarely, only cutaneous abnormalities are present in focal dermal hypoplasia. In one case the lesions formed at the sock line,965 although this may be an unrelated condition. Individuals with the syndrome are sensitive to ionizing radiation, with one study showing accumulation of p53 in exposed cells 3. endobj 178 likes. 11.14).913 The dermis may resemble a scar.914 Elastic fibers may be reduced, increased, or fragmented.915 Appendages are absent or rudimentary.916 The subcutis is usually thin. endobj Focal dermal hypoplasia (FDH, MIM #305600), also known as Goltz syndrome or Goltz-Gorlin syndrome, is an X-linked dominant multisystem disorder that is lethal in utero in males [].The primary feature of FDH is patchy dermal hypoplasia, with herniation of fat through defects in the dermis. This is a page for Brycen. Recognition of these characteristic features will permit early appropriate genetic counseling and treatment. In mice and Drosophila, the protein has been shown to be required for secretion of WNT proteins needed for activation of target genes in many developmental pathways. Dorothy Katherine Grange, in Emery and Rimoin's Principles and Practice of Medical Genetics, 2013. Recurrence risks for a female affected with an X-linked dominant disorder lethal in males. Goltz syndrome is a genetic condition primarily found in females that affects the appearance and function of the skin. Some patients may have only skin changes or simply syndactyly, whereas others may show full manifestations of the syndrome with microphthalmos, bilateral coloboma of the iris, ectopia lentis, hypoplasia of the teeth, and severe cutaneous, skeletal, and digital malformations. Myron Yanoff MD, Joseph W. Sassani MD MHA, in Ocular Pathology (Seventh Edition), 2015, Anetoderma and bilateral subcapsular cataracts, J. Cook, in Reference Module in Biomedical Sciences, 2014. This syndrome is distinct from focal dermal hypoplasia, but it could be included with focal facial dermal dysplasia (see below). Mutations in affected individuals have included nonsense, frameshift, missense mutations, as well as deletions of the entire gene (113). 2 0 obj <> This gene is part of the WNT pathway, as seen below. It is characterized by keratocystic odontogenic tumors (KCOT) in the jaw, multiple basal cell nevi carcinomas and skeletal abnormities. Acrodermatitis chronica atrophicans may coexist with juxta-articular fibrotic nodules and morphea-like lesions.995–997, Restrictive dermopathy (OMIM 275210) is a recently delineated, lethal, autosomal recessive disorder characterized by taut and shiny skin with facial dysmorphism, arthrogryposis multiplex, and bone dysplasia.998–1005 It has also been called the tight skin contracture syndrome. The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome-NBCCS) is a rare autosomal dominant syndrome caused due to mutations in the PTCH (patched) gene found on chromosome arm 9q. As a consequence, if an affected female were to have children, one would expect a sex ratio of 2:1, female to male, in the offspring and that one-half of the females would be affected, while none of the male offspring would be affected (Fig. Telangiectasia and hypo- and hyperpigmentation are seen. The unique case with membranocystic degeneration of collagen fibers, associated with some deposition of fat, and with the clinical appearance of xanthomatosis, defies classification.858. The reticular dermis is reduced in thickness only after prolonged topical therapy. There is marked thinning of the dermis with finger-like projections of fibrous tissue extending into the underlying subcutis. The syndrome, characterized by increased predisposition to develop basal cell carcinoma and associated multiorgan anomalies, has a high level of penetrance and variable … Digital anomalies include syndactyly, polydactyly, camptodactyly, and absence deformities. endstream ��k���4��"s��_ʯ����"�� Elastic fibers are focally crowded. Technical artifacts in the preparation of histological sections can also influence dermal thickness. Topical corticosteroids, especially potent forms, may thin the skin or produce striae. An unrelated syndrome, This question is designed to distinguish congenital disorders (e.g., aplasia cutis congenita, focal dermal hypoplasia) from acquired disorders (e.g., photoaging, lichen sclerosus). Focal dermal hypoplasia (FDH; OMIM 305600) has been observed almost exclusively in females; however, there are reported cases of affected males (190,191). *"��ءC�NZ�hm�ڵ�'7�4�J�9���DF'��P� �� �ND�_XP�01s>-C�KUI̅N� s&Il��AB First described in 1894, the clinical manifestations of NBCCS were more clearly defined in 1960 by Gorlin and Goltz [ 2 ]. 4 0 obj By continuing you agree to the use of cookies. Gorlin-Goltz syndrome is an uncommon autosomal dominant inherited disorder, which is characterized by multiple odontogenic Keratocysts and basal cell carcinomas, skeletal, dental, ophthalmic, and neurological abnormalities, intracranial ectopic calcifications of the falx cerebri, and facial dysmorphism. Herzberg and Wiskemann (1963) described what they termed the 'fifth phakomatosis,' basal cell nevus syndrome with medulloblastoma. It is a multisystem disorder characterized primarily by skin manifestations to the atrophic and hypoplastic areas of skin which are present at birth. The age of the patient is also relevant, since there is some atrophy of the skin in the elderly. It is an autosomal dominant syndrome with complete penetrance and variable expressivity. The underlying dermis is usually thin and composed of loosely arranged connective tissue in which there is some disarray of collagen fibers (Fig. The term ‘keratosis pilaris atrophicans’ refers to a group of three related disorders in which keratosis pilaris is associated with mild perifollicular inflammation and subsequent atrophy, particularly involving the face. x�� �����o̾��8@�( If atrophy is present the collagen bundles may appear thin and lightly stained.984 At other times the collagen appears homogenized.985 In some areas fibroblasts are decreased in number.

GTR Test ID Help Each Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. In conclusion, Goltz syndrome is a rare congenital skin disorder characterized by a unique clinical presentation which is FDH. Transposition of the great arteries and microcolon are two further associations.1006, Fibroblasts show poor growth in culture, suggesting that restrictive dermopathy results from a primary abnormality in fibroblast growth and function.998, A study in 2005 showed that restrictive dermopathy is caused by mutations either in the LMNA gene, at locus 1q21.2 encoding A-type lamins, or in the zinc metalloproteinase STE (ZMPSTE24) gene, encoding a metalloprotease essentially for the posttranslational processing of prelamin A to mature lamin A. The lesions are similar to atrophoderma of Pasini and Pierini but lesions in this latter entity do not follow Blaschko's lines. <> Listen. Focal dermal hypoplasia, or Goltz Syndrome, is a rare genetic x-linked autosomal dominant disorder. There is usually a microdeletion at Xp22,892 resulting in defects in the HCCS (human holocytochrome C synthase) gene.893,894 The gene for focal dermal hypoplasia is nearby (see below). Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome (NBCCS) was first described in 1894 by Jarish and White, but better defined by Gorlin and Goltz in 1960. Goltz syndrome is due to mutations or deletions of the PORCN gene which is located at Xp11.23. The superficial dermis often has a loose texture and there may be telangiectasia of superficial vessels. Inheritance was autosomal dominant. Localized atrophy may be caused by corticosteroid injections (intradermal or intramuscular). The variants that cause classical Rett syndrome are lethal in males; however, other variants in the gene can give a pattern of neuroencephalopathy and profound intellectual impairment in males that behaves as an X-linked recessive condition—another example of genotype–phenotype correlation.

It has been suggested that a postzygotic mutation in lamin A is a theoretical possibility as a candidate gene.991,992. It is an autosomal dominant syndrome with complete penetrance and variable expressivity. Clinical features include cutaneous changes, skeletal defects, digital malformations, ocular anomalies, and oral/dental anomalies (192). Elastic tissue may be increased in this region. There may also be a reduction in the size of the dermal appendages.986. Some atrophic conditions foment quickly (e.g., striae distensae, anetoderma due to steroid injections) whereas others may develop over months, years, or decades (e.g., poikiloderma atrophicans vasculare, intrinsic aging, photoaging).

DISCUSSION. Nevoid basal cell carcinoma syndrome (NBCCS) leads to the growth of non-cancerous and cancerous tumors. Aplasia cutis congenita is the term applied to a heterogeneous group of disorders in which localized or widespread areas of skin are absent at birth. 9 0 obj 1,2 It is a rare disorder due to mutation in the patched tumor suppressor gene PTCH, located in chromosome 9q22.3q31, which functions as a component of the Hedgehog signaling pathway. Despite the syndrome’s manifestations being predominantly cutaneous, the visual system also suffers characteristic alterations that are worthy of better elucidation. 164(3):126–30, 2005) Presence of two major criteria or one major and two minor criteria Major criteria Multiple (>2) basal cell carcinomas, or one diagnosed under 20 years The MIDAS (microphthalmia, dermal aplasia sclerocornea) syndrome is another distinct variant of aplasia cutis congenita presenting as linear facial skin defects. 1c Qcr�b0._��`E��!�x70h���I� 1�EedqAA%� ��(F�m��i�_��~�U�U]�3�߹g����v����^$$~3�%���_������沛�|��ԉ����S�̌����cpr�Zx�b���h�v�]���=���Z�d4���ѩ�FK29)Ia\�v�]��pE��@���}Ey������Ho�5�ժ3� �;�ޭ���n蕓�-5I��ŭ�����}{�{��Ry�U������)�fY���3:o�P�% _���U֮�����Z���r�`�X��L��������M�fզMU+�"neY���V���/-5oudS�r�mU"���F ��#:�������%��qv'��' �!t���FR-. �Ƙ�ca��;k�f�i��6a�Z��I��l�iw�I�]�Xcs���P]�S��5/h0��c�|����r�n�:o=ͷb8��g^�Mq�5�p�y�=t�0���d V��/R2辧�> �1�_J���Z�{��ß�̩˜Z����Ns�^�J���#�O�rF碉�� �5�j�Ur�X�U4��6�9�4~w�gn� ���k�lYi�D�-�G�;"�d��o�����PA���Ҧ|�Ѕ~�Þ�� �]������)�H����#��A� The Xp deletion syndrome, MLS (microphthalmia with linear skin defects) syndrome (OMIM 309801), and Gazali–Temple syndrome are similar conditions.891 It is lethal in males. Testing is available for ODDD syndrome. Injections of insulin, vaccines, antibiotics, of other injectable agents of any type may cause atrophy, especially if injected in the same area, for an extended duration, or with a suboptimal technique. Sequencing of the PORCN gene should be performed in females, followed by deletion testing by FISH or array CGH if no mutation is found. Cognitive abilities are typically intact for the majority of affected individuals. The dermis is usually thinned in striae distensae (see p. 319) but, because of the scar-like features, this condition has been considered with the hypertrophic collagenoses. 148.13.5.2 Genetics and Diagnosis. The amniotic band syndrome is a similar condition.964 Closely related are the raised linear bands that developed in the first few months of life in a few patients with localized constriction. James E. Fitzpatrick MD, ... W. Lamar Kyle MD, in Urgent Care Dermatology: Symptom-Based Diagnosis, 2018. Acquired lesions developing later in life may occur in association with scleroderma, psoriasis, syringomyelia, leprosy, and pachyonychia congenita.966,967. Prenatal and pre-implantation diagnostic testing are both available if the disease-causing mutation is known in the family. Most individuals have short stature and can have vertebral anomalies leading to kyphosis and scoliosis. <> Clinical molecular testing is available for the PORCN gene. 5 0 obj In 2007, Grzeschik et al. Clusters of adipocytes may be anywhere in the dermis or in a perivascular location.946 The extreme degree of attenuation of the collagen seen in focal dermal hypoplasia is not present in nevus lipomatosus, in which mature fat also replaces part of the dermis; furthermore, the clinical presentations of the two conditions are quite distinct. It affects multiple organs and systems, generally unilaterally, with extensive clinical variability. %PDF-1.5 There is also a reduction in adnexal structures and factor XIIIa-positive dendrocytes. Experimental studies using fibroblasts from affected skin have shown that synthesis of collagen by individual fibroblasts is normal, but that there is an abnormality in cell kinetics with reduced proliferative activity of fibroblasts.944 An absence of collagen type IV from the basement membrane zone has been reported.927,945. Goltz syndrome is due to mutations or deletions of the PORCN gene which is located at Xp11.23. <> endobj Differences in the location and the degree of atrophy have been used to categorize these three conditions – keratosis pilaris atrophicans faciei (ulerythema ophryogenes), keratosis follicularis spinulosa decalvans and atrophoderma vermiculata (folliculitis ulerythematosa reticulata). Brycen’s NFED conference and Goltz Syndrome Page. Cutaneous atrophy is an important complication of the long-term topical application of corticosteroids, especially if occlusive dressings are used or the steroids are fluorinated preparations.968–970 The injection of corticosteroids into the skin will also produce local atrophy;971,972 rarely, atrophic linear streaks develop along the lines of the overlying lymphatic vessels draining the injection site.973–976 Telangiectasia and striae are other complications that may develop.977,978. Girls with classical Rett syndrome have severe mental retardation developing after a period of relatively normal development. Nails may be absent, hypoplastic, dystrophic, spoon-shaped, or grooved. Focal dermal hypoplasia (Goltz or Goltz–Gorlin syndrome – OMIM 305600) is a rare syndrome with multiple congenital malformations of mesoderm and ectoderm, affecting particularly the skin, bones, eyes, and teeth.917–921 It is caused by mutations in the gene encoding the human homologue of Drosophila melanogaster Porcupine (PORCN), an endoplasmic reticulum protein involved in the secretion of Wnt proteins, which are important for the development of affected organs in focal dermal hypoplasia.922–924 The gene maps to Xp11.23. Analysis of additional cases by Grzeschik, Leoyklang and others has identified a variety of missense, nonsense and splice site mutations in the PORCN gene, confirming that this is the gene responsible for Goltz syndrome (110,112). endobj The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. Dermal atrophy is an inconstant and disputed feature. They also may abnormalities in the nails, hands, and feet. The collagen fibrils are reduced in size with irregular interfibrillary spaces and some granulofilamentous deposits.999,1000 Degenerating fibroblasts have also been noted. The PORCN gene encodes the human homolog of Drosophila porcupine. David Weedon AO MD FRCPA FCAP(HON), in Weedon's Skin Pathology (Third Edition), 2010. It is a type of ectodermal dysplasia, a group of heritable disorders causing the hair, teeth, nails, and glands to develop and function abnormally. Two publications have attempted to define distinct clinical subtypes, based on the location of the skin defects and the presence of associated malformations (Table 11.1).863,877 Some cases have an autosomal dominant inheritance with reduced penetrance of the gene;895 others appear to be the result of gene mutation.863,896 The condition has been reported in one of monozygotic twins.897 Other factors that may be etiologically significant in individual cases include amniotic adhesions, intrauterine trauma, drugs, particularly the antithyroid drug methimazole (thiamazole),898–900 biomechanical forces from the hemispheric growth of the brain,901 and ischemia resulting from placental infarcts902 or associated with the condition fetus papyraceus.877,885,903 A case mimicking aplasia cutis congenita, but resulting from a congenital nevus, has been reported.904, The defect in the skin presents as an ulcer, a membranous or bullous lesion, or an area of atrophic scarring.905 Sometimes there is a ring of coarse, long hair surrounding the scalp defect (the ‘hair collar sign’).906–908 Dermal melanocytosis was present in one such case.909 Lesions on the scalp usually heal with cicatricial alopecia.910 An abnormal tendency to cutaneous scarring has been reported in two siblings with this condition.911, Skin dimpling, which may be confused with aplasia cutis congenita, has been reported as a complication of second trimester amniocentesis.912. J. Pediatr. 8 0 obj There is often a spectrum of associated facial anomalies.952 The tetralogy of Fallot was present in one case.955 Inheritance is usually as an autosomal dominant trait with incomplete penetrance;956 other patterns of inheritance have been reported in what are probably clinical variants.957 A ‘hair collar’ may surround the defect.958,959 This entity has been regarded in the past as a variant of aplasia cutis congenita915 or as an ectodermal dysplasia.960, A specific variant of facial lesion that indicates the close relationship between focal facial dermal dysplasia and aplasia cutis congenita is the preauricular skin defect characterized by oval, atrophic patches distributed in a linear pattern on the preauricular region of the face.961 It is thought to be the result of a persistent ectodermal groove in the region of the fusion between the maxillary and mandibular facial prominences.961, The epidermis is thin and usually depressed.
