Early onset basal cell carcinoma: Consider Bazex-Dupré-Christol syndrome.

Bazex-Dupré-Christol syndrome is a rare genetic condition characterised by basal cell carcinomas, follicular atrophoderma and hypotrichosis. Until recently the molecular basis of the condition was largely unknown. A recent study has identified a section of duplicated DNA on the X chromosome of those with the condition which appears to be the underlying cause of the syndrome.
