Cellular Blue Nevus of the Finger: A Case Report

ABSTRACT

We experienced an unusual case of the cellular nevus on the dorsal surface of the second metacarpophalangeal joint. We performed a local excision followed by immunohistochemical analysis. Cellular blue nevus should be considered in the differential diagnosis when a characteristic blue-black mass is found in the finger. Accurate diagnosis based on immunohistochemical analysis, appropriate surgical treatment and vigilant follow-up are mandatory to prevent any malignant transformation.
