Аннотация
AIMS: Perivascular epithelioid cell tumor (PEComa) is a mesenchymal neoplasm originating from perivascular myoid cells. We report a case of PEComa arising from the ciliary body.
METHODS: Case report.
RESULTS: A 13-year-old girl was referred to our department with a clinical diagnosis of ciliary body melanoma in her right eye. Her visual acuity was 20/600 OD. Slit-lamp examination revealed a brown tumor behind the iris. The ocular fundus could not be observed due to a cataract. Ultrasonography depicted an oval mass approximately 10 mm in diameter at the ciliary body. The tumor was successfully treated by local resection, and the patient's visual acuity improved to 20/20. Histopathological and immunohistochemical findings of the excised tumor were compatible with the diagnosis of PEComa of the ciliary body. No local recurrence of the tumor was observed for over 4 years after surgery.
CONCLUSION: A very rare case of PEComa of the ciliary body was successfully treated by local resection, with favorable visual outcome and no recurrence for several years. PEComa can be differentiated from other ciliary body tumors by immunohistochemical study.
