Epithelial-Myoepithelial Carcinoma Presenting as a Pseudo Veno-Lymphatic Malformation.

A 41-year-old woman presented with several days of right eye pain and blurred vision. Examination and radiologic workup were consistent with a veno-lymphatic malformation, including demonstration of cystic fluid-fluid levels on imaging. Histopathology supported the presence of cystic spaces but revealed the final diagnosis of lacrimal epithelial-myoepithelial carcinoma, a rare neoplasm typically associated with the salivary gland. This represents the first reported case of lacrimal epithelial-myoepithelial carcinoma presenting with pain and evidence of intralesional cysts on radiographic and histopathologic evaluation. Better characterization will enable recognition, complete surgical excision, and potential adjuvant radiation therapy.
