Multiple Cutaneous Squamous Cell Carcinomas on Primary Epidermodysplasia Verruciformis in a 19-Year-Old Black Subject

Epidermodysplasia verruciformis (EV) is a rare genodermatosis characterized by chronic human papillomavirus infection of the skin and a risk of carcinomatous degeneration. We report a case of EV complicated by multiple cutaneous carcinomas of the scalp in a 19-year-old subject.

A 19-year-old male, phototype VI according to Fitzpatrick's classification, was referred to the dermatology department of CHU Kara with multiple painful tumoral lesions of the scalp that had been evolving for about 1 year. Clinical examination revealed hypochromic macules (Pityriasis versicolor-like), hypochromic verrucous flat papules scattered over the face, scalp, neck, trunk, and upper limbs. These lesions were associated with occasional pruritus. Apart from these lesions, there were three ulcerative-bourgeonous tumors on the scalp. A normal blood count was obtained, and the HIV serological test was negative. Histological examination of lesion biopsies confirmed the diagnosis of squamous cell carcinoma for all three lesions. Patient management was limited by lack of financial resources.

As sub-Saharan Africa is characterized by fragile health systems and high solar gradients, particular emphasis must be placed on preventive measures for skin cancers in patients with genodermatoses at risk of degeneration.
