Abstract:
Mesangiolytic glomerulopathy is an uncommon complication of irradiation and chemotherapy of THP-COP [pirarubicin, cyclophosphamide (CPA), vincristin (VCR), predonisolone (PSL)] and CHOP (CPA, Doxorubicin, VCR, PSL). We report a case of 63-year-old man 7 months status post radiation, and 10 months post chemotherapy for gastric lymphoma. The patient showed proteinuria and mild renal insufficiency. Renal biopsy revealed marked mesangiolysis in the glomeruli without any immune depositions. After the administration of angiotensin II receptor blocker, the patient's renal function remained stable for over two years. Mesangiolysis was thought to be a characteristic glomerular lesion in this patient treated with both chemoagents and radiation.
