Pigmented variant of benign oncocytic lesion of the pharynx.

A case of pigmented variant of benign oncocytic lesions is reported. The lesion was incidentally found in the pharynx of a 69-year-old man, and the gross appearances were multiple, small, flat elevations with black discoloration. Microscopically, ducts of seromucinous glands were replaced by melanin-containing oncocytes and adjacent dendritic melanocytes. To date, such a pigmented variant of benign oncocytic lesion has not been reported before.
