Primary Mucinous Adenocarcinoma of the Lower Eyelid

Abstract

Purpose: We report a case of a primary mucinous adenocarcinoma of the lower eyelid diagnosed in patient with a painless mass. Case summary: A 62-year-old male visited our clinic with a painless mass of the left lower eyelid of increasing the size for 2 months. Orbital computed tomography and magnetic resonance imaging revealed an approximately 2 cm well-defined ovoid, homogeneous enhancing mass in the left lower eyelid. A biopsy was performed under general anesthesia, and histopathologic examination confirmed mucinous adenocarcinoma. Final diagnosis was made as primary mucinous adenocarcinoma since torso positron emission tomography and computed tomography found no abnormal findings and extensive resection was performed for complete resection of the tumor. Conclusions: Primary mucinous adenocarcinoma that occurs in the eyelid is a very rare malignant tumor, and a systemic examination to determine whether it is metastatic is essential, and due to its high local recurrence, regular follow-up after extensive resection is required.
