Abstract
- Dermal melanocytosis is characterized by an increased number of ovoid to elongated melanocytes situated between collagen fibers in the dermis, including blue nevus, Mongolian spots, nevus of Ota and Ito and dermal melanocyte hamartoma. Herein, we present a rare case of a 15-year-old boy presented with both dermal melanocyte hamartoma and Becker's nevus in conjunction with neurofibromatosis. A shared pathophysiologic mechanism between neurofibromatosis and other nevi in the context of organoid hamartoma has been reviewed.
