Abstract
A 52-year-old female had a nephrotic syndrome without neurological or dermatological manifestations. Renal biopsy revealed that glomeruli were filled with tumor cells which bore leukocyte common antigen and pan B cell marker. These cells occupied the capillary lumen and invaded into the mesangial area. Morphological alteration of endothelial cells and glomerular basement membrane were also noticed. The interstitium was well preserved. After five cycles of a combination chemotherapy, CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone), the second biopsy revealed that tumor cells disappeared from glomeruli showing mild sclerosis. Proteinuria became absent. This is the first report of an angiotropic large cell lymphoma manifesting a nephrotic syndrome and treated successfully by CHOP therapy.
