A case of episcleral neurofibroma

Purpose: To report a rare case of episcleral neurofibroma and discuss the p ossible differential diagnoses. Methods: Case report of a 36-year-old man w ho presented with a painless epibulbar mass of the left eye. We describe th e clinical and histopathologic features of the tumour and compare it with o ther tumours which may have a similar clinical presentation. Results: An ex cisional biopsy of the tumour was performed. Histopathologic examination re vealed the tumour to be an isolated episcleral neurofibroma. Conclusion: It is often difficult to clinically differentiate this tumour from other cond itions. Because of the slow growth of neurofibromas and its slow risk of ma lignant transformation, these lesions may be observed periodically for prog ression. Surgical excision may be performed if the lesion is found to be pr ogressively enlarging in size.
