title: [Renal Epithelioid Angiomyolipoma with Spontaneous Rupture: A Case Report].
abstract: A 66-year-old woman was referred to our hospital for a right renal mass found in the examination for sudden right flank pain. Abdominal computed tomography (CT) revealed a right renal tumor, 8.0 cm in diameter, with massive hemorrhage due to spontaneous tumor rupture. After transcatheter arterial embolization, right radical nephrectomy was successfully performed. The histopathological diagnosis of the renal tumor was epithelioid angiomyolipoma (eAML). Postoperative chest CT showed two lung tumors. Therefore, the lung tumors were resected and diagnosed as a primary lung adenocarcinoma and a sclerosing angioma. Although renal eAML is thought to have malignant potential, there has been no local reccurence nor distant metastases of renal eAML 11 months after the surgery.
