Squamous Cell Carcinoma Presumebly Orignating from the Lacrimal Sac

MR in squamous cell carcinoma of the lacrimal sac.

A case of squamous cell carcinoma arising from the right lacrimal sac is presented. MR T2-weighted images showed a mass of low signal intensity in the right medial canthus extending into the nasolacrimal duct. This led us to postulate a high-grade malignant neoplasm arising in the lacrimal sac.

Carcinoma of the lacrimal sac.

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.

Squamous cell carcinoma arising from a Sebaceous cyst

      Abstract: development of squamous cell carcinoma from sebaceous cyst is uncommon.in this report , we report a77- old female patient who has had a sebaceous cyst for 20 years. The cyst started to grow during the last year. The patient underwent an operation for excision biopsy and The diagnosis was squamous cell carcinoma.

Adenoid cystic carcinoma of the lacrimal sac: case report.

Lacrimal sac tumors are rare with a clinical presentation that typically includes obstruction of the lacrimal drainage system and epiphora as the most frequent symptom. Cribriform adenoid cystic carcinoma (ACC) is the most common malignant epithelial tumor of the lacrimal gland and minor salivary glands; however, its occurrence in the lacrimal drainage apparatus is extremely rare. Given the rar...
