[Intraocular perivascular epithelioid cell tumor: report of two cases]

Two male patients presented with painless vision loss to blindness in one eye, and the radiography examinations revealed an intraocular mass suspicious for choroidal melanoma. They underwent enucleation. The histopathological and immunohistochemical findings were compatible with the diagnosis of intraocular perivascular epithelioid cell tumor. Because of its rarity, intraocular perivascular epithelioid cell tumor is easy to be confused with other intraocular tumors on histopathological and immunohistochemical examinations.
