Nevus lipomatosus (pedunculated lipofibroma) of the eyelid.

Nevus lipomatosus is a rare connective tissue nevus characterized by mature adipose tissue within the dermis. An 11-year-old boy presented with an eyelid papule that had been observed expectantly since birth and had exhibited gradual and progressive enlargement. Excisional biopsy revealed a polypoid mass formed of mature adipocytes within the dermis and subconjunctival mucosa consistent with nevus lipomatosus. This is the first case of nevus lipomatous to our knowledge to be reported on the eyelid. Nevus lipomatous or pedunculated lipofibroma can arise on the eyelid and should be considered in the differential diagnosis of eyelid tumors.
