PURPOSE: A 31-year-old woman with a mass at the left inner canthus was referred to our hospital. METHODS: Clinical examination failed to establish a diagnosis and the patient underwent an incisional biopsy. RESULTS: Histopathologic examination disclosed a hemangiopericytoma. CONCLUSIONS: Because the behavior of a hemangiopericytoma is unpredictable, this tumor should be included when making a differential diagnosis in lesions of the inner canthus.
