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 ...

A benign encapsulated fibroma within the right lacrimal sac was found to be the cause of nasolacrimal obstruction in a 75-year-old man. This rare tumour was completely excised through an incision for a routine dacryocystorhinostomy, which could then be done.

Analysis of dacryoliths removed at operation showed that most consisted of calcium. One consisted of ammonium and could be directly related to the presence of bacteria. Tear samples obtained from 14 patients with dacryoliths were compared with seven normal patients with regard to calcium, phosphorus, and uric acid concentrations, tear to serum calcium ...

Lacrimal diverticula are cystic outpouchings, mostly communicating with the lacrimal sac [1–5]. An abnormal cellular cord stem from the lacrimal sac region during embryogenesis could contribute to diverticula. Diverticula of the lacrimal sac can be congenital, inflammatory, or post-traumatic [1].
