Sarcomatoid mesothelioma: Unusual findings and literature review

Abstract

Sarcomatoid mesothelioma is an aggressive disease secondary to its propensity to undergo rapid growth, show inconsistent expression of tumor markers and invade surrounding tissues. Therefore, there are numerous obstacles that clinical researchers face as they look for new methods to diagnose and treat the malignancy. We present a case of sarcomatoid mesothelioma, originally thought to be metastasis from renal cell carcinoma.
