A 12-year-old female presented with multiple milia and skin-coloured papules over face and neck, follicular atrophoderma and hypotrichosis. Family history of similar complaints present in mother and maternal aunt. Biopsy from the skin-coloured papule revealed trichoepithelioma. Multiple milia, hypotrichosis and follicular atrophoderma favour the diagnosis of Bazex-Dupre-Christol syndrome (BDCS) which is an X-linked dominant genodermatosis with BCCs developing later in life. Other conditions with multiple BCCs and milia like Gorlin syndrome, Oley syndrome and Rombo syndrome should be differentiated. Follicular atrophoderma and hypotrichosis with X-linked dominant inheritance favour the diagnosis of BDCS. Management should focus on identifying BCCs at the earliest and genetic counselling.

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.

Conradi-Hünermann-Happle syndrome (CHHS) is a rare genodermatosis resulting from mutations in the EBP (emopamil binding protein) gene. Dermatologic manifestations may include cicatricial alopecia, ichthyosis, follicular atrophoderma, pigmentary abnormalities, and nail dystrophy. In addition to genetic testing and clinical findings, trichoscopic findings may aid in the diagnosis.

Background: Bazex-Dupré-Christol syndrome (BDCS; MIM301845) is a rare X-linked dominant genodermatosis characterized by follicular atrophoderma, congenital hypotrichosis and multiple basal cell carcinomas (BCCs). Previous studies have linked BDCS to an 11·4-Mb interval on chromosome Xq25-q27.1.
