Hyperkeratotic Bowen disease--a case report.
A 70-year-old woman of Indian descent, with Fitzpatrick type IV skin type, presented with a 1-year history of a hyperkeratotic facial plaque. She also exhibited numerous signs of chronic sun damage. Hyperkeratotic squamous cell carcinoma in-situ was diagnosed after skin biopsy. It is important to remember that darkly pigmented patients do develop skin cancers.
