Abstract

Different types of multinucleated melanocytes have been described in benign and malignant melanocytic lesions. Here we describe a relatively common, though underappreciated, type of multinucleated melanocyte characterized by abundant vesicular and fibrillary-appearing cytoplasm containing one or multiple eosinophilic inclusion bodies. In our experience, these vesicular multinucleated melanocytes with inclusion bodies are invariably seen in nevi of long duration. The presence of these cells can be a reassuring histological finding when evaluating a melanocytic lesion.
