Rare transitional cell carcinoma of the lacrimal sac

Transitional cell carcinoma of the nasolacrimal sac

Tumors in the lacrimal sac are rare yet important due to their malignant and potentially lethal outcomes if there is a misdiagnosis or delay in treatment. Epithelial tumors predominate with squamous cell carcinoma. We report a transitional cell carcinoma of the lacrimal sac and management course for the patient.

Management of transitional cell carcinoma of the lacrimal sac: a multidisciplinary approach to orbit sparing treatment.

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.

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.
