[Mesenteric recurrence of leiomyosarcoma of the kidney seven years after the first operation - a case report].
A 60-year-old woman presented to our hospital with a pelvic tumor detected by using computed tomography at the Department of Urology of another hospital. Her medical history indicated that she had undergone left nephrectomy and left hemicolectomy for a tumor of the left kidney 7 years previously. Leiomyosarcoma of the left kidney was diagnosed on the basis of the histopathological examination at the previous hospital. Recurrence of leiomyosarcoma was suspected, and a second operation was performed. A mesenteric tumor was detected. Leiomyosarcoma recurrence was diagnosed on the basis of another histopathological examination. The patient remains free of disease and recurrence 3 years after the second operation. Primary leiomyosarcoma of the kidney is a rare disease, even among renal tumors. The prognosis of leiomyosarcoma of the kidney is poor because of frequent metastasis and recurrence. Radical resection is the preferred first choice for treatment, but recurrence still occurs frequently. In our case, the mesenteric recurrence was detected 7 years after the first operation. There have been no previous reports of mesenteric recurrence of leiomyosarcoma of the kidney. Although histopathological and immunohistochemical examinations indicated a poor prognosis, the patient is alive and there are no signs of recurrence 3 years after the second operation.
