Abstract
- Papillomatous melanocytic nevus is a clinical type of melanocytic nevus, which show a resemblance to seborrheic keratoses both clinically and histopathologically. Therefore, this kind of nevi is also described by the terms of keratotic melanocytic nevus and seborrheic wart-like melanocytic nevus. Characteristic histopathologic findings include epidermal acanthosis, hyperkeratosis, papillomatosis, a lacelike and downward growth of epidermal strands, and horn cysts. We present four cases of papillomatous melanocytic nevi in 3 females and 1 male patients, which did not express estrogen receptors in immunohistochemical study.
