Renal mucinous tubular and spindle cell carcinoma, abbreviated RMTSCC, is a rare malignant epithelial neoplasm of the kidney.
It is also known as renal mucinous tubular spindle cell carcinoma and mucinous tubular and spindle cell carcinoma of the kidney.[1]
General
Gross
Features:[4]
- Solid.

Microscopic
Features:[5]
- Mucin (foamy macrophages) - may be scant.
- Spindle cells - key feature.
- Small tubules - lined by cuboidal epithelium.[4]
DDx:
- Sarcomatoid papillary renal cell carcinoma[6] (papillary renal cell carcinoma with sarcomatoid differentiation).
- Papillary renal cell carcinoma.
