title: Protruding tumorous angiolymphoid hyperplasia with eosinophilia (ALHE) of the scalp accompanied by arterial occlusion.
abstract: We report a case of an extraordinarily large tumorous form of ALHE developing on the occiput of a 57-year-old Japanese male. Histologically, it was characterized by increased numbers of small blood vessels, fibrosis, and lymph follicle formations with massive eosinopilia in the dermis in addition to an occluded artery in the deep dermis.
