Primary pleural thymoma with coexistent incidental small hepatocellular carcinoma - an autopsy case report with brief review of literature.

Primary pleural thymomas are rare tumors often mistaken for malignant mesothelioma clinically and radiologically. An autopsy case report of primary pleural thymoma associated with a coincidental small hepatocellular carcinoma is presented. This case is reported because of the rarity of pleural thymoma and the coincidental finding of a small hepatocellular carcinoma in a non-cirrhotic background. The literature on these two tumors has been reviewed.
