Abstract

PURPOSE
The tumor of lacrimal sac is very rare. We report an experience of a 63-year-old female who had a squamous cell carcinoma of the lacrimal sac and discuss its diagnosis and overall management. METHODS: A 63-year-old woman came to our clinic with a 2-month history of a growing mass in the region of the left medial canthus, left eye tearing. Examination revealed left epiphora and swelling on the left medial canthus and the left lacrimal sac, which was firm. Lacrimal irrigation indicated an obstruction. A computed tomographic scan demonstrated a well enhancing soft tissue mass in medial aspect of left orbit and no evidence of invasion of rectus muscles and adjacent bony destruction. The mass was excised by dacryocystectomy and subsequently, required 200 cGy a day, 5 times a week, 6000 cGy of radiotherapy for 6 weeks.
RESULTS
The patient was finally diagnosed with keratinizing, squamous cell carcinoma that was proven by histopathologic finding. There was no evidence of recurrence of the tumor in lacrimal sac throughout 24 months of follow-up period.
