Observation of Angiolymphoid Hyperplasia with Eosinophilia (ALHE) at Three Arterial Sites and Its Association with Membranous Nephropathy.

We herein report a case involving the systemic presentation of angiolymphoid hyperplasia with eosinophilia (ALHE) in association with membranous nephropathy (MN). A 34-year-old Japanese man presented with leg edema and bilateral temporal nodules. He had a history of Buerger's disease and recurrent coronary stenosis. A renal biopsy performed to assess nephrotic syndrome revealed MN. Furthermore, a temporal nodule was excised, and ALHE was diagnosed. We reevaluated the coronary and posterior tibial artery specimens obtained in his twenties and presumed that these lesions were also vascular tumors arising from ALHE. The association of ALHE and MN is quite rare.
