Squamous cell carcinoma of the lacrimal sac.

Squamous cell carcinoma of the lacrimal sac is rare. We report a case of a 45-year-old Caucasian woman with a squamous cell carcinoma of the right lacrimal sac, initially presenting at an early stage. A critical review of the literature is also presented with specific regard to operative and postoperative management. Treatment of these lesions is predominantly surgical. The role of radiation therapy is not yet fully defined. Successful management requires a high index of suspicion as well as aggressive and early intervention.
