Oncocytomas of the lacrimal gland are rare tumors. We report the first documented case in Nigeria. This was an interventional case report. A complete ophthalmologic and systemic examination with available pertinent investigations was done, followed by a modified exentheration and histopathologic examination. A 60-year-old Nigerian housewife was evaluated for a slow-growing, right upper lid mass associated with visual lesion in the ipsilateral eye. Plain skull x-rays revealed a soft tissue in the right eye orbit without any bony extension. A modified exentheration was done. Histopathology showed sheets of oxyphil cells in the lacrimal gland. Although rare, more cases of oncocytomas may exist than are reported in the literature.
