Mucinous tubular and spindle cell carcinoma of the kidney
Tóm tắt
Mucinous tubular and spindle cell carcinoma (MTSCC) is a low-grade renal epithelial neoplasm that has recently been recognized as a specific entity in the 2004 World Health Organization classification of renal cell carcinoma. A 69-year-old woman was referred to our hospital because of incidental left renal tumor. Abdominal computed tomography showed a hypovascular tumor in the left kidney. Left radical nephrectomy was performed. Hematoxylin and eosin staining revealed cuboidal and oval or spindle-shaped cells in tubular and papillary patterns embedded in the myxoid stroma. Immunohistochemically, the tumor cells were positive for alpha-methylacyl-CoA racemase. On the basis of these findings, we diagnosed the patient as having MTSCC.
