Giant renal angiomyolipoma: A case report.

Renal angiomyolipoma (AML), also referred to as renal hamartoma, is a rare solid tumor without malignant characteristics. The inheritance pattern of renal AML is autosomal dominant. If the lesion grows to a large size, a series of clinical manifestations and serious complications may occur. We herein present a case of giant renal AML in a 34-year-old female patient, who presented with left-sided abdominal bloating for ~6 months. Following abdominal ultrasound and computed tomography examination, the patient underwent total left nephrectomy. The resected mass was sized 29×20x10 cm. Postoperative histopathological examination confirmed the lesion as a giant renal AML. There are only few cases of giant renal AML (>20 cm) reported in the literature to date. Due to the large size of the tumor, it is crucial to report similar cases, their diagnosis and treatment.
