Lacrimal Sac Septum

Orbit, 2012
A right orbit was exenterated from a male cadaver that was 85 years of age at death. It was microscopically shown for the first time that the lacrimal sac septum divided the lumen into two spaces. It consisted of fibrous tissue with a cavernous structure and was lined with stratified columnar epithelium similar to the lacrimal sac wall.

Lacrimal Sac Melanoma

Ophthalmic Plastic & Reconstructive Surgery, 2007

Congenital lacrimal sac diverticulum

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2020
We report the case of a 6-month-old boy with recurrent episodes of acute dacryocystitis from age 3 months to 1 year of age. The cause was determined to be congenital nasolacrimal sac diverticulum, a rare and commonly asymptomatic entity. An isolated diverticulectomy without dacryocystorhinostomy was performed because of lacrimal drainage system patency.

American Journal of Ophthalmology, 1982
Seven infants had tense, blue-gray swellings inferior to the medial canthal tendon with otherwise normal-appearing eyelids and puncta. All lacrimal sacs transilluminated and A-scan ultrasonography performed in one case demonstrated a nonloculated cystic cavity. Four (57%) infants had uncomplicated mucoceles.

Hemangiopericytoma of the Lacrimal Sac

Archives of Ophthalmology, 1998
Hemangiopericytoma (HPCT) rarely originates in the lacrimal sac; 7 cases have been reported previously and only 1 contained an ultrastructural study. In this article we report an additional case and review the previous reports. While the initial biopsy specimen showed nonspecific cytologic abnormalities, light and electron microscopic studies on the ...
