Atypical Presentation of a Pigmented Oncocytoma of the Caruncle: A Case Report

Abstract

We report an unusual case of a pigmented oncocytoma of the caruncle. The lesion presented the following atypical features: a well-circumscribed, partially pigmented, and lobulated mass that macroscopically resembled a caruncular nevus. However, an excision biopsy revealed an oncocytoma instead. Thus, although nevi are the most common lesions found in the caruncle, oncocytoma should also be considered in the differential diagnosis of a pigmented caruncular mass, especially in elderly female patients.
