A 33‐year‐old man was hospitalized for treatment of a left renal tumor. The radiological findings were consistent with those of a left renal cell carcinoma (RCC). Subsequently, a radical nephrectomy was carried out. Macroscopic examination showed that a well‐demarcated tumor measuring 2.9 × 2.6 × 2.5 cm was present in the middle portion of the resected kidney. The cut surface of the tumor was grayish‐white in color. Pathological examination of the resected specimen showed a mucinous tubular and spindle cell carcinoma of the kidney (MTSCC‐K). MTSCC‐K is a low‐grade renal epithelial neoplasm that has recently been recognized as a specific entity in the World Health Organization 2004 classification of RCC. To our knowledge, 17 cases of MTSCC‐K in Japan have been reported by Japanese investigators. To avoid administration of excessive adjuvant treatment to patients, pathologists and urologists should consider this newly recognized low‐grade malignancy when diagnosing renal tumors.
