A Case of Angiolymphoid Hyperplasia with Eosinophilia / 대한피부과학회지

ABSTRACT

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign tumor, characterized by marked proliferation of endothelial cells. ALHE shows histopathologic feature of extensive infiltrate of lymphocytes, histiocytes and numerous eosinophils, and occurs on the head and neck of young adults. We report a case of ALHE in a 49-year-old woman. Histopathologic examination revealed lymphoid follicles with germinal centers and proliferation of irregular capillaries with plump endothelial cells, sometimes atypical in appearance, protruding into the lumen of the blood vessels.
