[Primary malignant tumors of the lacrimal sac and nasolacrimal duct].
To assess the clinical characteristics, the workup, therapeutic approach and pathological findings of primitive tumors of the lacrimal sac. Three cases were retrospectively reviewed from the database of our ENT department. They were analyzed and compared to cases reported in the literature. One adenoid cystic carcinoma and two adenocarcinomas were observed, all were adults and the sex ratio was one man for 2 women. Clinically they presented neither significant lacrimal or rhinologic sign. A CT-scan and a MRI were performed along with a physical examination. An entire surgical resection was done with subsequent postoperative radiotherapy. Two patients died, and one is alive, free of disease. Lacrimal tumors should be considered in the differential diagnosis of a banal chronic epiphora. The ENT practitioner must associate this factor to any clinical evaluation. The management of these lesions requires a complete surgical resection, routinely associated with postoperative radiation.
