Abstract
The term chronic dacryocystitis is usually referred to the inflammatory process that occurs in the lacrimal sac following a nasolacrimal duct obstruction of more than 6 months of duration. The histopathological changes include epithelial thickening, denuded epithelium, metaplastic epithelium, stromal fibrosis, stromal hyalinization, luminal stagnation of secretions and denuded cellular debris, loss of distinct acinar patterns, increased goblet cell density, mostly atrophic and occasional hypertrophic mucosal glands, proliferative blood vessels, and dilated lymphatics [1–5].
