Stereotactic radiosurgery as a successful method to control meningeal metastatic adenoid cystic carcinoma of the lacrimal gland: A case report.

Adenoid cystic carcinoma (ACC) of the lacrimal gland is a rare tumor. In addition, considering the lack of data on large groups of patients there is no standard of care to treat patients with multiple meningeal metastases of ACC. A two-year analysis of the course of the disease in a patient with synchronous oligometastatic ACC of the lacrimal gland that was treated with stereotactic radiosurgery (SRS) is presented. The aim of the present case report was to evaluate the effect of SRS in the treatment of a patient with ACC. Preliminary results confirmed that this method was highly effective in this patient. The patient is currently living with a good quality of life, normal vision and with no evidence of disease or complications. SRS exhibited reliable local tumor control and insignificant radiation-related complications, rendering it an encouraging treatment option for patients with recurrent or metastatic ACC.
