title: Hemangiopericytoma of the conjunctiva. Two cases.
abstract: Two patients with hemangiopericytoma of the conjunctiva are reported. The first patient, a 40-year-old woman with a six-month history of a conjunctival mass, presented with a lesion confined to the conjunctiva. The second patient, a 43-year-old man, presented with a one-year history of a conjunctival mass. Excisional biopsy and histopathologic examination showed both lesions to be a hemangiopericytoma; an uncommon tumor of the conjunctiva.
