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 ...

Hemangiopericytoma of the Lacrimal Sac

Ophthalmic Surgery, Lasers and Imaging Retina, 1992
ABSTRACT 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.

Novel Evidence Concerning Lacrimal Sac Movement Using Ultra-High-Frequency Ultrasound Examinations of Lacrimal Drainage Systems

Ophthalmic Plastic and Reconstructive Surgery, 2020
Purpose: Current hypothesis regarding the mechanism of active tear drainage is based on studies performed ex vivo or under nonphysiological conditions. Novel ultra-high-frequency ultrasound has the advantage of generating images with superior resolution,

Argyrosis of the lacrimal sac

Graefes Archive for Clinical and Experimental Ophthalmology, 1987
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.
