ABSTRACT
BACKGROUND: Nevoid basal cell carcinoma syndrome (NBCCS, Gorlin-Goltz syndrome) presents various symptoms and can disfigure patients. The estimated prevalence is around 1:100,000. OBJECTIVE: To systematically investigate the clinical manifestations of NBCCS patients of the Zurich register and compare them with those described in 4 epidemiological studies performed in other countries. METHODS: We analyzed patient characteristics and clinical manifestations in a register of 30 NBCCS patients in Zurich, Switzerland. We compared our findings to the results of 4 epidemiological studies performed in America, Australia, Japan and the UK. RESULTS: We obtained information concerning basal cell carcinomas (BCCs) and jaw cysts from 28 patients out of our population of 30 NBCCS patients. The mean age at onset of the first BCC was 24 years, and the mean age at diagnosis of the first jaw cyst was 15.6 years. The average number of jaw cysts was 8.4; the average number of BCCs was 207. 72.5% of the examined BCCs showed a nodular histology, but we also found scirrhous and superficial types. CONCLUSION: The disease burden associated with NBCCS diagnosed in Swiss patients is significant and comparable to that of other countries. Regular skin examination and oromaxillary examinations should be performed early in diagnosis, and patients should undergo early UV protection. Nodular BCC is the most common BCC subtype in this patient population.

People living in poor conditions are at high risk of developing different medical diseases of which dermatological diseases are very common. We present 4 clinical cases of skin diseases, which are the most prevalent amongst the majority of socially and economically vulnerable patients. Early diagnosis and appropriate treatment are of paramount importance, in order to avoid their spread in close- knit communities where these patients often live.
