Eyelid Lipoma

Purpose: To report a rare case of eyelid lipoma. Case summary: A 41-year-old female presented with a palpable mass in her left upper eyelid. Diffuse hard mass was palpable at preaponeurotic fat layer of left upper eyelid, and there was no inflammatory sign. Under local anesthesia, a left upper eyelid mass partial excision was performed and a biopsy specimen was collected. The mass was yellower and harder than surrounding normal eyelid fat. A lipoma was diagnosed based on histopathological findings such as proliferation of mature adipocytes. Conclusions: Lipoma is a benign tumor commonly found around trunk and limbs, but rarely occurs at eyelid. Eyelid lipoma should be considered as a differential diagnosis of diffuse mass at eyelid fat layer. Diagnosis and treatment can be achieved by partial excision and histopathological examination.
