I have a report with biopsies from perineal mass and urethral mass with a diagnosis of Sarcomatoid Carcinoma. From my understanding, this is an uncommon form of cancer of malignant cells with properties of both epithelial tumors as well as mesenchymal tumors. Therefore, I am unsure whether to use "carcinoma" of the organ site or the "sarcoma" of the connective tissue.
Any thoughts would be greatly appreciated.
