Benign mixed tumor of the lacrimal sac.

ABSTRACT

Neoplasms of the lacrimal drainage system are uncommon, but potentially life‑threatening and are often difficult to diagnose Among primary lacrimal sac tumors, benign mixed tumors are extremely rare. Histologically, benign mixed tumors have been classified as a type of benign epithelial tumor. Here we report a case of benign mixed tumor of the lacrimal sac.
