Renal mucinous tubular and spindle cell carcinoma
Renal cell carcinoma
Mucinous tubular and spindle cell carcinoma (MTSCC) is a rare subtype of renal cell carcinoma. Although usually indolent, high-grade MTSCC has been reported to exhibit an aggressive clinical course. Herein, we report a case of high-grade renal MTSCC. An 86-year-old man visited our hospital with fever and fatigue. Based on contrast-enhanced computed tomography findings, the patient was diagnosed with clinical stage T2aN0M0 right renal cell carcinoma and underwent laparoscopic radical nephrectomy. Histological examination showed tubular to tubulopapillary structures accompanied by mucinous stroma, suggesting high-grade renal MTSCC. He remained recurrence- and metastasis-free 6 months after nephrectomy. Since high-grade renal MTSCC may have an aggressive clinical course, such patients should be observed carefully after radical nephrectomy.
