Xanthelasma in Medical term

Xanthelasma palpebrarum manifests as yellowish fibrotic plaques on the eyelids, resulting from the deposition of cholesterol-laden histiocytes in the dermis. Histologically, xanthelasmas are composed of xanthoma cells, or foam cells, which are typically found within the middle and superficial layers of the dermis in perivascular and periadnexal locations, with evidence of concurrent fibrosis and inflammation. In some cases, xanthelasma can infiltrate the muscle layer and muscle resection is required for complete excision of the lesion. In this study, muscular infiltration was seen in approximately 25% of patients. Incomplete excision of the lesion leads to a higher incidence of recurrence.

Numerous treatment options, both local and systemic, have been reviewed in the Past, including surgical resection; ablation with various lasers such as carbon dioxide, erbium-YAG, pulsed dye , and Nd-YAG; trichloroacetic acid peels; and treatment of the underlying medical condition. However, each method of treatment is associated with limitations and complications such as persistent erythema, recurrence, ectropion, scarring, and hypo- or hyperpigmentation . Mendelson and Masson found that 40% of patients had a recurrence after primary surgical excision, 60% after secondary excision, and 80% when all four eyelids were involved. Mendelson and Masson did not mention lesion extension in regard to depth, and may not have acquired an adequate resection depth margin in the surgical treatment of xanthelasma palpebrarum, accounting for their relatively high recurrence rate. However, this was not discussed in their paper, and it is difficult to draw conclusions.

Xanthelasma palpebrarum has been correlated in some cases with the presence of an underlying medical condition, and therefore, systemic treatment of the underlying medical condition with lifestyle modification or pharmaceutical therapy can be attempted before or in conjunction with surgical excision. In lesions with only a superficial extent, laser therapy may suffice, but in some cases, surgery may provide a more aesthetic result. In such cases, treatment should be individualized in each case. In conclusion, among the numerous treatment options for xanthelasma, we have found that for lesions involving the deep dermis and/or muscle, surgical excision was the most appropriate therapeutic option. In diffuse lesions, excision in conjunction with local flaps or skin grafts provided aesthetic reconstruction with a low incidence of recurrence
