Abstract:
It is uncertain whether small congenital melanocytic nevi is associated with an increased risk of melanoma. However, if a small congenital melanocytic nevus develops suspicious changes, becomes symptomatic, or is irregular, then an excisional biopsy may be justified. We report an interesting case of a 33-year-old man who was diagnosed with melanoma in situ, arising in a small congenital melanocytic nevus with a cyst. Histologic examination revealed that intradermal nests of nevus cells had surrounded the epidermal cyst. In the basal cell layer, and in the wall of the epidermal cyst, atypical melanocytes were observed.
