Eyelid xanthoma is a benign tumor of the eyelid that often occurs in middle-aged and older adults and is a disease of the eyelid in ophthalmology.
It can occur in diabetes mellitus and other secondary hyperlipidemia, hereditary hyperlipidemia, and most people have normal blood lipids. It is usually located in the upper eyelid near the medial canthus, but can also be seen in the lower eyelid, and is often bilateral.
Histologically, it is a slightly elevated, flattened yellow spot with a clear border with the surrounding normal skin and a soft texture. Microscopically, it can be visualized as containing focal aggregates of adipose-containing histiocytes within the superficial layers of the skin, mainly surrounding blood vessels and papillary reticular dermal adnexal structures, and never spreading to the subcutis.
Treatment is usually not required, and blood lipids can be checked. If you want to remove the yellow tumor for aesthetic reasons, you can go to the ophthalmology department for surgical excision treatment.
