Nonepithelial Tumors of the Lacrimal Sac.
Ophthalmic Plastic & Reconstructive Surgery, 1994Lacrimal sac tumors are rare and mostly of epithelial origin. We conducted a clinicopathologic study of 35 cases of nonepithelial tumors of the lacrimal sac. These tumors included 13 fibrous histiocytomas, one hemangiopericytoma, one lipoma, ten lymphoid lesions, eight malignant melanomas, one granulocytic sarcoma, and one neurofibroma.

Malignant Melanoma of the Lacrimal Sac
Otolaryngology–Head and Neck Surgery, 1995Although malignancies of the lacrimal sac are rare, malignant melanoma of the lacrimal sac is an exceedingly rare occurrence. Patients with abnormalities of the nasolacrimal system may come to otolaryngologists for evaluation. Treatment of lacrimal sac malignancies will necessitate consultation of a head and neck surgeon. The triad of symptoms commonly
