Abstract: 【Abstract】 A 34-year-old female patient presented with itchy nodules on the left posterior ear for 7 years. Skin examination showed clustered light-red or brown-black nodules measuring about 4 cm × 5 cm in size on the left posterior auricle, as well as from the posterior sulcus of the auricle to the anterior border of the hair line on the posterior auricle. Histopathological examination of the skin lesion revealed epidermal hyperkeratosis, proliferation of a lot of small blood vessels in the dermis, swelling vascular endothelial cells with enlarged nuclei and eosinophilic cytoplasm bulging into vascular cavity, and perivascular infiltration of lymphocytes and many eosinophils. The patient was diagnosed with angiolymphoid hyperplasia with eosinophilia. After extended surgical resection, a skin graft from the left lower abdomen was used to repair the defect. After the surgery, the flap survived well, and the appearance of the auricle was improved. No recurrence was observed during 1 year of follow-up.
