title: [A case of perirenal encysted hematoma secondary to renal cell adenocarcinoma].
abstract: Herein we report a case of perirenal encysted hematoma secondary to renal cell adenocarcinoma. A 57-year-old woman was hospitalized because of a palpable mass in the left flank. She had had an episode of left flank pain. X-ray studies demonstrated a tumor in the left kidney and a large cystic mass beneath the left kidney. The cyst was excised by nephrectomy. Histological examination of the large cyst revealed perirenal encysted hematoma secondary to renal cell adenocarcinoma. Six months postoperatively, she is now free from left lumbar pain, and alive with lung and liver metastasis.
