Neurofibroma of the lacrimal sac
Orbit, 2002Neurofibroma is an extremely rare neural tumor of the lacrimal sac. We present a case of neurofibroma of the lacrimal sac in a 45-year-old lady. Based on the history of intermittent epiphora, presence of a mass in the lacrimal sac region, dacryocystogram suggestive of space occupying lesion within the lacrimal sac and computed tomographic image of a ...

This is a clinicopathologic study of 115 lacrimal sac neoplasms in adults (mean 52 years). The most common presenting signs and symptoms were epiphora (53%), recurrent dacryocystitis (38%), and/or lacrimal sac mass (36%). The tumors were divided into epithelial (82 cases) and nonepithelial (33 cases) neoplasms.

Sarcoidosis of the Lacrimal Sac
Archives of Ophthalmology, 1982To the Editor. —In an article in the JulyArchives(1981;99:1198-1201), Harris et al described two patients with sarcoidosis of the lacrimal sac and reported that there were only seven cases, including theirs, reported in the literature so far. Because they seem to have missed my study 1 concerning 281 patients with histologically verified sarcoidosis ...

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.

Journal of Pediatric Ophthalmology & Strabismus, 1980
A case of fibroma arising from the anterolateral wall of a healthy lacrimal sac on the left side in a 22-year-old male is reported. There was no epiphora. The tumor presented as a painless, nonreducible swelling in the lacrimal sac region. It was excised off leaving a patent sac.

Hemangiopericytoma of the Lacrimal Sac
Archives of Ophthalmology, 1998Hemangiopericytoma (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 ...

Hemangiopericytoma of the Lacrimal Sac
Ophthalmic Surgery, Lasers and Imaging Retina, 1992ABSTRACT Hemangiopericytoma is a rare soft-tissue neoplasm composed histologically of pericytes. Hemangiopericytoma of the lacrimal sac is exceedingly rare. This case provided the first known computed tomographic image of a hemangiopericytoma of the lacrimal sac prior to surgical intervention.

De novo papillary squamous carcinoma of the lacrimal sac
Auris Nasus Larynx, 2003 We report a rare case of a papillary squamous carcinoma of the lacrimal sac diagnosed at first presentation. The initial presentation of the patient discussed here mimicked that of a lacrimal sac mucocele.

Silver deposition in the wall of the lacrimal sac after prolonged application of mild silver protein (Argyrol) eye drops is documented at the light and electron microscopical level. Silver granules were found in the extracellular matrix predominantly on elastic fibres and within cells forming conglomerates in secondary lysosomes.
