Abstract
- Nevus with cyst is defined as a single lesion in which there is the coexistence of an epidermoid cyst and a melanocytic nevus. Similar clinical and histopathologic changes can be observed when a hair follicle ruptures and subsequent folliculitis with supprative granulomatous reaction occurs beneath a melanocytic nevus. This cystic change due to inflammation is a different pathologic phenomenon from the formation of an epidermal cyst. Hence, it is necessary to differentiate between these two conditions. We report here on a case of congenital melanocytic nevus combined with cystic change due to inflammation in a 39-year-old man.
