Pigmented epithelioid melanocytoma: A rare tumor
Pigmented epithelioid melanocytoma is a poorly understood and rarely reported skin tumor which mimics melanoma and whose diagnosis is based on clinical, histological and immunohistochemical arguments. We report the case of a young 24-year-old patient who consulted for the sudden appearance of a plaque and then a black nodule on the left cheek, gradually increasing in size, painless and slightly infiltrated. Dermoscopy could not decide between a nodular melanoma or a blue nevus given the intensity of the pigmentation. Anatomopathological examination of the piece revealed a pigmented epithelioid melanocytoma or animal-type melanocytoma. The consequences of the complete excision were simple without recurrence after a follow-up of 9 months. It is a borderline affection, its diagnosis and treatment are necessary in order to avoid any unforeseeable malignant evolution.
