title: Dacryocystectomy for tumors of the lacrimal sac.
abstract: A high index of suspicion is very important in the early diagnosis and treatment of potentially lethal tumors of the lacrimal sac. The triad of a mass above the medial canthal tendon, chronic dacryocystitis which irrigates freely and bloody reflux on irrigation should alert the ophthalmologist of this potentially fatal situation. Complete surgical excision and postoperative irradiation are important in the treatment of malignant tumors.
