[A case of muscle metastasis of renal cell carcinoma treated by local resection and tensor fascia lata myocutaneous flaps].

A 44-year-old male with a little finger tip-sized tumor palpable on the left epigastric wall and a left renal tumor detected on computerized tomography (CT) was referred to this hospital in June 1991. Nephrectomy was performed in July 1991 under the diagnosis of a left renal tumor. Histologically, the tumor was a renal cell carcinoma, grade 2, clear and granular cell type. The tumor in the left abdominal wall was not extracted. As a tumor also developed in the scapular tunica muscularis, tumors in the left musculus rectus abdominis and the scapular tunica muscularis were extracted to the extent possible in July of 1992. Histologically, these tumors were metastatic clear cell carcinomas. The tumor in the left musculus rectus abdominis recurred and another was palpable in the left lateral femur. In August of 1993, the tumors in the left musculus vastus lateralis and the left musculus abdominis were extracted together with the tunica muscularis, and the defective region on the abdominal wall was closed with a left musculus tensor fascia lata flap. No evidence of recurrence has been observed to date.
