          Abstract

          RESUMO O oncocitoma é um tipo de neoplasia rara na prática clínica e descrito na literatura, principalmente quando localizado no olho. Quando localizado nos anexos oculares, é mais frequentemente na carúncula. Analisou-se o caso de uma paciente de 74 anos, caucasiana, que relatou desconforto visual no olho esquerdo, e cujo exame físico mostrou lesão tumoral na carúncula esquerda, com volume moderado, presença de neovascularização e secreção excessiva. A excisão cirúrgica da lesão foi realizada sob sedação, e a peça foi enviada para avaliação anatomopatológica. A lesão foi diagnosticada histologicamente como oncocitoma, sem malignidade, e a paciente não apresentou recidiva após o procedimento. Embora raro, esse tumor deve ser reconhecido pelos oftalmologistas, devido ao risco já relatado de desenvolvimento de adenocarcinoma.

          ABSTRACT Oncocytoma is a neoplasm rarely observed in clinical practice and reported in the literature, especially when located in the eye. When described in the ocular adnexa, it is most often located in the caruncle. The case of a 74-year-old Caucasian female patient is reported. She complained of visual discomfort in the left eye, and physical examination showed a tumoral lesion in the left caruncle, of moderate volume, presence of neovascularization, and excessive secretion. Surgical excision of the lesion was performed under sedation, and the specimen was sent for pathological examination. The lesion was histologically diagnosed as oncocytoma with no malignancy, and the patient presented no recurrence after the procedure. Although rare, this tumor must be recognized by ophthalmologists due to the risk of developing adenocarcinoma, as already reported.

              Oncocytic lesions of the caruncle and other ocular adnexa.

              This is a clinicopathologic study of 18 oncocytic lesions involving the ocular adnexa. These lesions most commonly occur in elderly patients (median age 73), and there is a striking predilection for women. The broad spectrum of lesions included oncocytic adenomatous hyperplasia, oncocytomas, and oncocytic carcinoma. Ten lesions, all of which were oncocytomas, involved the caruncle, four the conjunctiva, and one the mucocutaneous junction of the eyelid. Two tumors involved the lacrimal sac and one the lacrimal gland. A review of the literature disclosed only 17 previously reported oncocytic lesions of the ocular adnexa. A small yellowish-tan or reddish caruncular mass, especially in an elderly woman, should alert the ophthalmologist to consider the possibility of oncocytoma in his differential diagnosis.
