Overview

Angiolymphoid hyperplasia with eosinophilia was first discovered by G. C. Wells and I. W. Whimster, two British physicians, in 1969.[1]Angiolymphoid hyperplasia with eosinophilia [2] is defined as red-brown, dome-shaped, dermal papule or nodule, present in the around the ears, scalp, neck, trunk, extremities, genitalia, lips and oral mucosa.[3]On gross pathology, smooth-surface red to brown papules or nodules are characteristic findings of angiolymphoid hyperplasia with eosinophilia. On microscopic histopathological analysis, florid vascular proliferation with atypical endothelial cells surrounded by a lymphocytic and eosinophilic infiltrate are characteristic findings of angiolymphoid hyperplasia with eosinophilia. Angiolymphoid hyperplasia with eosinophilia may be caused by either allergic reactions, traumas, or autoimmune disorders. Angiolymphoid hyperplasia with eosinophilia must be differentiated from other diseases that cause swelling of face and neck, such as Kimura disease, acial granuloma, insect bite reaction, cutaneous lymphoma, sarcoidosis. The prevalence of angiolymphoid hyperplasia with eosinophilia is unknown as it is an extremely rare disease. Angiolymphoid hyperplasia with eosinophilia is more commonly observed among young patients. Females are more commonly affected with angiolymphoid hyperplasia with eosinophilia than males. Angiolymphoid hyperplasia with eosinophilia usually affects predominently individuals of the Asian race. Common complications of angiolymphoid hyperplasia with eosinophilia include pruritis, pulsation, and spontaneous bleeding. Findings on biopsy include proliferation of small blood vessels with endothelial cells having a cobblestone appearance, a perivascular and interstitial infiltrate of lymphocytes and eosinophils. Surgery is the mainstay of therapy for angiolymphoid hyperplasia with eosinophilia.
