Cutaneous oncocytoma - a report of three cases and review of the literature.
The oncocyte is a cell characterized by capacious, eosinophilic, finely granular cytoplasm, and lesions composed primarily of oncocytes are termed oncocytomas. Whereas oncocytic metaplasia has been reported in various cutaneous neoplasms, oncocytomas typically occur in the kidneys, thyroid and salivary glands and are uncommon in the dermatopathology literature. We present three cases of cutaneous oncocytoma so that dermatopathologists are cognizant of this uncommon entity. Although some believe that oncocytomas are locally aggressive lesions, our cases indicate that their clinical course is perhaps as banal as their histology.
