Focal dermal hypoplasia: A novel finding in disguise.

ABSTRACT: Focal Dermal Hypoplasia (FDH) or Goltz-Gorlin syndrome is an unusual X-linked dominant syndrome characterised by anomalies of both ectodermal and mesodermal structures. We present a case report on the management of a 58 year old Caucasian male with Focal Dermal Hypoplasia. This report describes an additional clinical manifestation of an intraosseous mandibular lipoma, which has not been previously described in cases of FDH. Intraosseous lipomas in the head and neck region are reported in only seventeen cases in isolation of any associated syndrome. Diagnosis was hindered due to similitude with Nevoid Basal Cell Carcinoma Syndrome (Gorlin-Goltz Syndrome) which despite similar nomenclature, is an exclusively separate condition This novel finding encourages clinicians to consider unusual differential diagnoses in such cases and highlights the importance of avoiding eponyms to prevent confusion with similar conditions.

Project description:Focal dermal hypoplasia (Goltz syndrome), is an extremely rare genetic disorder characterized by distinct skin manifestations and a wide range of abnormalities involving the ocular, dental, skeletal, urinary, gastrointestinal, cardiovascular, and central nervous systems. The objective of the present series is to emphasize the different typical as well as unusual features of this rare syndrome.This cross-sectional observational study was performed over a period of 8 years in a tertiary care hospital of Eastern India. Consecutive patients with the clinical diagnosis of Goltz syndrome were studied.A total of 8 patients with Goltz syndrome were evaluated. Out of them, one patient was a boy and the rest were girl. The age ranged from 3 days to 9 years. There was no family history. A characteristic Blaschkoid hypo- and hyper-pigmented skin lesions, congenital nodular fat herniation, and skin atrophy were present in all patients. Congenital cutaneous aplasia was present in 50% of the patients. Facial asymmetry and ear deformity (megalopinna and low-set ears) were seen in 37.5% and 12.5% of patients, respectively. Cutaneous telangiectasia was noticed in 37.5% of patients. Freckle- and lentigines-like pigmentation within the hypopigmented macules was found in 25% of patients. Raspberry-like papillomas around mouth were documented in 6 (75%) patients. Dysplastic nail changes with ridging were seen in 7 (87.5%) patients. Genital abnormality in the form of bilateral undescended testes and microphthalmia with aniridia were found in one patient each. Limb defects were present in all patients. Left-sided renal agenesis was found in one patient. The patient also had multiple cortical cysts of the right kidney.Genetic testing could not be performed in the present series.Our case series showed a few unusual or extremely rare manifestations such as undescended testes, dermal sinus, kyphoscoliosis, aniridia, unilateral kidney agenesis, and renal cortical cysts among others.
