A Lacrimal Gland Choristoma of the Lacrimal Sac.

Choristomatous lacrimal gland tissue has been detected in many different sites of the ocular adnexa, but has never before been convincingly described in the submucosa of the lacrimal sac. A 77-year-old woman with epiphora had a biopsy of the sac wall preformed during a dacryocystorhinostomy that contained such a lacrimal choristoma. Zymogen granules were found in the cytoplasm of the secretory cells with the periodic acid-Schiff reaction. No mucus-producing cells, as found in normal sac submucosal glands, were detected using the Alcian blue, mucicarmine, and Gomori methenamine silver histochemical stains. Gross cystic fluid protein-15 positivity was demonstrated immunohistochemically. The clinical implications of this choristoma are explored.
