title: Squamous cell carcinoma of the lacrimal sac.
abstract: Diagnosis to differentiate successfully an uncommon epidermoid carcinoma of the lacrimal sac from the commoner acute inflammation of the lacrimal sac requires a good history and thorough physical examination. If epidermoid carcinoma of the lacrimal sac is suspected, additional procedures including a dacryocystogram, orbital tomograms, plain films and CAT scans, and otolaryngologic consultation are necessary. Such a successful diagnosis of an epidermoid carcinoma of the lacrimal sac is reported here. An aggressive surgical approach is described and strongly recommended because review of the literature shows that the prognosis for these tumors is very grave.
