[Squamous cell carcinoma associated with use of skin-lightening cream]

Women widely use skin-lightening products for cosmetic purposes in sub-Saharan Africa despite numerous reported cutaneous and systemic complications. The occurrence of epidermoid carcinoma has long been reported, but only three cases have been published so far. We report the first case in Mali.

A 30-year old woman with no noteworthy medical history was seen at our outpatient center for cervical ulceration that had been present for the last 5 years. She had used cosmetic bleaching cream over a period of around ten years. Physical examination revealed extensive ulceration on the left side of her neck. Blood tests for viral hepatitis and human immunodeficiency virus were negative. The pathological examination of the skin biopsy confirmed the diagnosis of squamous cell carcinoma. After failure of the initial excision with early relapse, multiple surgical ablations were performed 3 months later.

The high prevalence of skin-lightening cosmetic use contrasts with the rarity of epidermoid carcinoma in depigmented skin. However, a large chronic ulcer on uncovered parts of the upper body, particularly the neck, should prompt physicians to consider skin cancer. Appropriate preventive measures include the promotion of educational messages for the general population, the use of sun-protection devices, and routine skin biopsy for all women presenting chronic cervical ulceration after long-term use of skin-lightening products.
