A case of angiolymphoid hyperplasia with eosinophilia treated with Nd:YAG laser / 中华皮肤科杂志

ABSTRACT

A 38-year-old male patient presented with multiple papules on the scalp with itching and tingling for 3 years. Skin examination showed multiple millet- to soybean-sized red papules on the scalp. Histopathological examination showed epidermal hyperkeratosis, mildly thickened prickle cell layer, proliferation of a large number of capillaries in the dermis, and perivascular infiltration of closely distributed lymphocytes and scattered eosinophils. The blood vessels were lined by hyperplastic and hypertrophic endothelial cells, some of which projected into the vascular cavity. The patient was diagnosed with angiolymphoid hyperplasia with eosinophilia. After 1 session of NdYAG laser therapy, all the skin lesions were removed, and no obvious adverse reactions were observed. No relapse occurred during 5 months of follow up.
