Mucinous Tubular and Spindle Cell Carcinoma of the Kidney with Nodal Metastasis Managed with Surgical Resection

Abstract

Mucinous tubular and spindle cell carcinoma (MTSCC) is a rare renal malignancy that usually follows an indolent course. The few existing reports of metastatic MTSCC show poor response to systemic therapy. Here we describe the unusual case of a 39-yr-old male with MTSCC presenting as a large renal mass with bulky retroperitoneal lymphadenopathy managed with complete resection of disease. He has remained free of recurrence for 1 yr postoperatively. On the basis of the experience reported here, aggressive surgical resection of MTSCC with isolated nodal metastases may be considered for similar patients in the future given the historically poor response rates to systemic therapy.
