Skin examination showed a 0.5\u20131\u2009cm red-pink, shiny, exophytic papule with visible telangiectasias near the anal verge. The differential diagnosis was most concerning for Kaposi sarcoma. A shave biopsy with electrodessication was performed for both diagnostic and therapeutic purposes. Histology revealed a dome-shaped lesion with a diffuse inflammatory infiltrate composed of lymphocytes and eosinophils. The vessels in the superficial and mid-dermis showed cuboidal-to-columnar endothelial cells with nuclear enlargement, conspicuous nucleoli, and ample cytoplasm. These findings were consistent with angiolymphoid hyperplasia with eosinophilia (ALHE). Only 2.4% of ALHE occur on the genitals and fewer than 1% on the buttocks. Additionally, few of these are reported in female patients and none in female patients with HIV. At 12 months post-treatment, the patient remains without evidence of recurrence.<\/jats:p>","DOI":"10.1136\/bcr-2024-263181","type":"journal-article","created":{"date-parts":[[2025,1,19]],"date-time":"2025-01-19T20:50:20Z","timestamp":1737319820000},"page":"e263181","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Perianal
