Abstract:
Pigmented Bowen's disease is characterized by microscopically increased melanin pigment in the epidermis and/or papillary dermis in addition to the typical findings of Bowen's disease. This disorder is infrequently reported and represents less than 2% of cases of Bowen's disease. Pigmented Bowen's disease is often confused clinically with pigmented lesions, such as seborrheic keratosis, melanocytic nevus, pigmented basal cell cacinoma and superficial spreading melanoma. A 74-year-old man presented with a black hyperkeratotic nodule overlying a solitary dark brownish patch on the scalp, this was clinically diagnosed as seborrheic keratosis. Histopathologic examination revealed pigmented Bowen's disease. We, herein, report an unusual case of pigmented Bowen's disease, which is the first reported case to have occurred on the scalp and to clinically resemble seborrheic keratosis.
