A case of primary adenocarcinoma of the lacrimal sac.

PURPOSE: To present a rare case of adenocarcinoma arising from the lacrimal sac.

DESIGN

Interventional case report.

METHODS

Report of a new case of primary lacrimal sac adenocarcinoma.

RESULTS

The clinical presentation, workup, surgical treatment and pathology of a case of adenocarcinoma of the lacrimal sac are described.

CONCLUSION

Although very rare, these tumors should be in the differential diagnosis of any lacrimal sac mass, especially those presenting above the medial canthal tendon. Other common features include expressible blood from the punctum, lack of pain, and a history of chronic epiphora or intermittent dacryocystitis. Local destruction and metastatic spread can be prevented by a high index of suspicion and early intervention.
