Abstract
- Pigmented Bowen's disease is an unusual form of squamous cell carcinoma in situ characterized by a hyperpigmented appearance, which is exceedingly uncommon and represents less than 2% of Bowen's disease. An 80-year'old woman developed a sharply demarcated, irregularly marginated, hyperpigmented plaque with a velvety surface on her perianal area. Microscopically, the cells of the stratum malphighii lay in a disordered pattern, and many cells were atypical. Increased melanin pigment was noted throughout the epidermis and in the upper dermis. We report a case of pigmented Bowen's disease developed on perianal area in an 80-year-old female patient
