Rhinosporidiosis of the Lacrimal Sac

Applied Endoscopic Anatomical Evaluation of the Lacrimal Sac

Introduction: Dacryocystorhinostomy (DCR), a popular surgical procedure, has been performed using an endoscopic approach over recent years. Excellent anatomical knowledge is required for this endoscopic surgical approach. This study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the Isfahan forensic center as a sample of the Iranian ...

Carcinoma of the lacrimal sac.

Hemangiopericytoma of the lacrimal sac.

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 subsequently excised tumor demonstrated that ...

Diverticulum of the lacrimal sac.

A woman aged 33 was admitted to the Unit on February 17, 1957. She had been referred by Mr. W. E.

Lacrimal sac mucoepidermoid carcinoma.

A single case of mucoepidermoid carcinoma of the lacrimal sac was considered worth reporting as there are only four other cases described in the literature. The importance of the correct histological diagnosis and the management are discussed. This appears to be the first study of the ultrastructure of lacrimal sac mucoepidermoid tumour.
