## Abstract

Mucinous tubular and spindle cell renal cell carcinoma (MTSRCC) is a rare subtype of renal cell carcinoma with distinctive histological features and generally favorable prognosis. We report the case of a 52-year-old woman who presented with right lumbar pain. CT and MRI revealed a well-defined solid renal mass with mild, homogeneous enhancement. The patient underwent tumorectomy, and histological examination confirmed mucinous tubular and spindle cell renal cell carcinoma. The favorable postoperative outcome in this case illustrates both the diagnostic value of imaging and histology and the good prognosis associated with MTSRCC.
