Aetiology
Xanthelasma is a yellowish or white fat deposit or plaque that occurs on the upper or lower eyelid, usually near the inner corner of the eye. It is a benign (non-cancerous) condition and is caused by an accumulation of cholesterol or lipids in the area.
Diagnosis
Xanthelasma is usually diagnosed with a physical exam by a doctor. In some cases, a biopsy may also be performed to confirm the diagnosis.
Differential diagnosis
Xanthelasma must be differentiated from other benign or malignant skin lesions such as sebaceous adenomas, melanocytic nevi, or basal cell carcinomas.
Treatment
Xanthelasma can be treated by surgical removal, laser therapy, or cryotherapy.
Prognosis
Xanthelasma typically does not cause any long-term problems, and the prognosis is generally good. However, recurrence is possible and should be monitored.
