Simple lipomas of the eyelid are rare. We present a case of a 61-year-old man, who presented with 6 months of a slowly worsening blepharoptosis. On examination, that patient was noted to have a palpable, soft mass in the medial left upper eyelid. Histopathological examination of the mass revealed mature adipose tissue most consistent with lipoma. Simple lipomas of the eyelid are very unusual but should be considered in the differential diagnosis of patients presenting with mechanical ptosis.
