Metastatic laryngeal carcinoma mimicking pleural mesothelioma

We describe an unusual case of metastatic poorly differentiated laryngeal carcinoma to the pleura resembling pleural mesothelioma in a patient with a positive history of exposure to asbestos. This case not only describes an unusual presentation of metastatic laryngeal carcinoma, but also highlights the need for special pathological techniques to distinguish nonmesothelial tumors from primary pleural mesotheliomas.
