Eosinophilic Cytoplasmic Inclusion Bodies in Vesicular Multinucleated Melanocytes: A Clue to the Diagnosis of Benign Melanocytic Lesions

The American Journal of Dermatopathology, 05/25/2012

The authors 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 the authors' 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.
