Canaliculorhinostomy following dacryocystectomy for removal of a benign fibrous histiocytoma of the lacrimal sac.

A 41-year-old woman had epiphora and a right lacrimal sac mass. A solid mass filling the entire lacrimal sac was found at surgery. After a month of testing and evaluation at the Armed Forces Institute of Pathology, the final diagnosis was benign fibrous histiocytoma. A dacryocystectomy was performed, and the entire tumor was removed. The area of the common canaliculus was then attached to a nasal mucosal flap, and the system was intubated with silicone tubing for 1 year. Two years after the tubing was removed, the epiphora had resolved and there was no recurrence of the tumor.
