BACKGROUND: Focal dermal hypoplasia (FDH) or Goltz syndrome is a rare genetic multisystem disorder characterized by hypoplasia of ectodermally and mesodermally derived tissues. No cases of development of basal cell carcinomas in patients affected by FDH have previously been reported.
METHODS: We followed a 38-year-old woman with FDH who developed, within a period of 3 years, 14 atypical pigmented lesions. All of them were surgically removed and pathologically assessed. In 2007, this patient underwent molecular examination with the multiple amplifiable probe hybridization technique.
RESULTS: Histopathological examination showed 6 basal cell carcinomas, 2 basaloid proliferations, 2 tumours of follicular infundibulum and 2 solar lentigines. Molecular examination showed that only 1 copy of the coding exons of PORCN and EBP, respectively, was present, reflecting a microdeletion of one of her X chromosomes, eliminating at least the neighbouring genes PORCN and EBP.
CONCLUSIONS: No other cases of association between FDH and multiple cutaneous basal cell carcinomas have previously been reported, so it could be interesting to take into consideration this aspect in the molecular assessment of these patients to improve information on the disease. This is a single case experience, and especially the molecular results need confirmation and validation by other groups involved in the diagnosis.
