[Pathological changes found in the lacrimal sac during nasolacrimal duct surgery]

Abstract

In the course of 489 external dacryocystorhinostomies one found: 19 pseudotumors (granulomas and inflammatory granulations), 6 true tumors (1 papilloma, 1 congenital cyst, 1 lymphoma), 6 cases of calcium deposits and stones and 1 case of epithelial metaplasia. The author points to a great number of pseudotumors which are the effect of a long-standing process of dacryocystitis treated conservatively without effect. She thinks that the surgical treatment should be undertaken as fast as possible.
