自然破裂した腎平滑筋肉腫の1例

Abstract

A case of renal leiomyosarcoma ruptured spontaneously is reported. A 36-year-old man was admitted to our clinic with the complaint of right flank pain. The urographic examination, including an excretory urography, renal CT-scan, renal angiography, and ultrasonography revealed a renal tumor with spontaneous rupture on the right side. A nephrectomy through the lumbal flank incision on the right side was performed on February 28, 1984, and histopathological diagnosis was renal leiomyosarcoma. Five courses of adjuvant chemotherapy, VCR, ADM and CPM, combined with maintenance immunochemotherapy using Tegafur and Krestin and with radiotherapy (3, 000 rad) were performed post-operatively. The patient was followed for 18 months after operation as an outpatient with no evidence of local recurrence and metastasis. The 40 reported cases including our case with leiomyosarcoma in Japan is reviewed and some characteristics of this entry are discussed.
