Fibrous histiocytoma of the lacrimal sac.

Abstract

Fibrous histiocytoma is a slow-growing tumor that most commonly occurs in the superficial and deep soft tissue, with an occasional occurrence in the orbit. However, fibrous histiocytoma of the lacrimal sac is very rare. A case report of a 33-year-old man with a palpable mass in the right lacrimal sac and epiphora is presented, with a review of the literature pertaining to this unusual case. The patient was found to have a 3 x 2-cm-sized mass in the right lacrimal sac. Under the impression of benign tumor, the tumor was excised. Histopathological diagnosis of fibrous histiocytoma was made on the surgical specimen. Following surgical treatment, the patient has remained free of symptoms. Fibrous histiocytoma of the lacrimal sac is a rare disease. This case report and a review of the literature demonstrated that surgical excision appears to control the tumor.
