Lésion d'Antopol-Goldman (Antopol-Goldman lesion): Spontaneous renal pelvic subepithelial hematoma

Abstract

Lésion d'Antopol-Goldman (Antopol-Goldman lesion) is a rare condition characterized by renal pelvic subepithelial hematoma simulating a neoplastic process. A 71-year-old lady presented with macroscopic hematuria and hypoenhancing mass lesion at the upper pole of left kidney. The patient underwent a radical nephrectomy for suspected renal cell carcinoma. Macroscopically a 3.5cm circumscribed hemorrhagic mass lesion was noted flush with the upper pole pelvicalyceal system. Microscopic examination revealed a pelvic subepithelial (suburothelial) organizing hematoma. Extensive sampling did not reveal any neoplastic etiology. The adjacent renal parenchyma and renal vessels were unremarkable. Antopol-Goldman lesion is a diagnostic quagmire, often culminating in unnecessary nephrectomy. This is a rare entity, and clinical awareness as a differential of renal filling defect can preclude a nephrectomy, we hereby discuss its clinico-pathological and treatment implications.
