Mucinous tubular and spindle cell carcinoma of the kidney: case report with literature review

Mucinous tubular and spindle cell carcinoma (MTSCC) of the kidney is a rare renal cancer type, recently recognized by the World Health Organization (WHO) in 2004, with indolent behavior. We present a case of a 50-year-old female that revealed a renal mass on an abdominal echography, incidentally discovered during a hepatic hemangioma follow-up. The patient underwent partial nephrectomy, and after pathological evaluation the final diagnosis of MTSCC was made. MSTCC is a special renal cancer type, with low degree of malignancy and a favorable prognosis. Surgical resection is the treatment of choice. It’s important to be aware of this entity in order to differentiate MTSCC with renal cancers of less favorable prognosis and higher degree of malignancy like papillary renal cell carcinoma.
