Purpose: To present a rare case of Primary Lacrimal Sac Melanoma, and review all reports of this condition in the literature to date. Methods: In this review the clinical characteristics, presenting symptoms, treatment and morbidity of all patients with lacrimal sac melanoma reported in the literature from 1926 to the present. We have also discussed new approaches available for adjuvant radioth...

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.

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.

A 31-year-old man with epiphora and mucous discharge from a traumatic lacrimal fistula underwent a computed tomographic dacryocystogram, revealing a fistula extending from the anterior ethmoid air cells through the lacrimal sac to the overlying skin with coexisting nasolacrimal duct obstruction. Endoscopic dacryocystorhinostomy enabled complete marsupialization of the lacrimal sac and agger nas...

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.

Acute dacryocystitis usually induces preseptal infection. In rare instances the infection that is confined to the lacrimal sac can extend to the orbital contents resulting in orbital cellulitis. We present a case of intraconal abscess secondary to acute dacryocystitis and review the literature of orbital cellulitis resulting from acute lacrimal sac infection.
