The epidermal or epidermoid cyst is a proliferation of epidermal cells within an enclosed space. It develops slowly and may be the result of either the inclusion of ectodermal remnants during the closure of the neural tube or epidermal inclusions following trauma or a surgical procedure. Discovered most often in adolescence or adulthood, the eyelid epidermal cyst presents as a painless swelling that progressively increases in size and is mobile. Eyelid location is predominantly in the upper tarsus due to retention of meibomian gland material. The authors report a case of a large inferior eyelid epidermal cyst of traumatic origin in a 24-year-old patient whose ultrasound examination had concluded to a hemangioma of the eyelid. The report of this case aims at highlighting its rarity, the interest of imagery and the modalities of management in an under medicalized context. •Epidermal cyst is a proliferation of epidermal cells within an enclosed space.•Epidermal cysts of traumatic origin of the lower eyelid is rare.•Its diagnosis is histological after surgical exeresis.•The bilobed form is a first in the literature.
