title: Isolated episcleral neurofibroma.
abstract: A 22-year-old white woman presented with an epibulbar tumor of the right eye first noted seven years previously. Clinical examination showed a 6 x 8 mm lobulated yellowish white tumor rising 3-4 mm off the inferior bulbar surface. An excisional biopsy revealed the tumor to be free of conjunctival attachments and be firmly fixed to the sclera. Smaller nodules were noted away from the main tumor and posterior to the equator. The histopathologic evaluation revealed the tumor to be an isolated episcleral neurofibroma. Although rare, isolated episcleral neurofibromas should be thought of in the differential diagnosis of epibulbar tumors and treated conservatively.
