Simple lipoma of the eyelid: a rare entity

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.

Preseptal Upper Eyelid Lipoma

Superficial subcutaneous lipomas are benign, slow-growing neoplasms comprised mature adipose cells that may be surrounded by a fibrous tissue capsule. While found commonly on the body, simple lipomas are rarely described in the eyelids. Reports of two eyelid lipomas in the literature describe the anatomy to be posterior to the orbital septum. The presenting authors report the case of a simple lipoma of the eyelid found fully in the preseptal plane. Lipomas can occur anterior to the orbital septum and should be considered in the differential when presented with a painless, slow-growing eyelid mass in adults.

Upper eyelid angiolipoma associated friction in the glide zone

A 74-year-old man was examined for a mass in the left upper eyelid. It was inconspicuous in inspection. There was no visual restriction, however a feeling of friction on the superior orbit during lid movement. Through eyelid crease lid incision, a solitary lesion appeared in the preaponeurotic space that orginated from the upper tarsal plate. Excisional biopsy revealed adipose proliferation with patch form vessels. This case represents the second reported angiolipoma of the eyelid in English literature.
