Eyelid Spindle Cell Lipoma: Case Report and Review of Three Patients in Literature.

A 39-year-old woman presented a saucer-shaped mass in the left upper eyelid and underwent the extirpation at local anesthesia. Pathologically, collagen fibers, capillaries, small vessels, and CD34-positive spindle cells were dispersed among mature adipose tissues, indicative of spindle cell lipoma. Long-lasting cyst-like eyelid masses would be usually dermoid cysts, and spindle cell lipoma would be listed as a rare pathological diagnosis in differential diagnoses of cyst-like lesions in the upper and lower eyelid.
