The authors report an unusual case of lung adenocarcinoma metastasis to the lacrimal sac. A 61-year-old woman with stage IV non-small cell lung cancer presented with left facial pain and epiphora. She was found to have an elevated tear meniscus associated with a firm, fixed medial canthal mass. Orbital imaging demonstrated nodular enlargement of the lacrimal drainage apparatus. Biopsy of the lacrimal sac was performed, and it revealed a metastatic lung adenocarcinoma. The patient received targeted radiation therapy to the lacrimal sac, and her dose of maintenance chemotherapy was increased. The patient's symptoms have since improved. This case of lung cancer involving the lacrimal sac highlights the importance of thorough oncologic surveillance, even with respect to locations atypical for metastatic spread.
