Membranous glomerulonephritis in a patient with choriocarcinoma: case report.

A 26-year-old woman presented at our hospital with pretibial edema, swelling, and vaginal bleeding. She had nephrotic-level proteinuria and was diagnosed with choriocarcinoma after a histologic examination of her uterine curetting was performed. The renal biopsy specimen was compatible with membranous glomerulonephritis. The renal pathology in this case was thought to be secondary to choriocarcinoma because the nephrotic syndrome regressed after hysterectomy. We briefly present this first case of choriocarcinoma causing membranous glomerulonephritis.
