A 57-year-old man with a chest wall tumor and right pleural effusion was referred to our hospital. Cytological analysis of the pleural effusion and biopsy of the parietal pleura had already been performed, but no fixed diagnosis was made. The chest wall tumor and the tissue along the tracts of the biopsy needles were removed, and a subsequent thoracoscopic examination was performed. The histological findings of the chest wall tumor led to a diagnosis of biphasic malignant mesothelioma. The clinical stage was T3N0M0 stage III on IMIG-TNM classification. A right extrapleural pneumonectomy was performed. In this case, the histological findings of the chest wall tumor facilitated the final diagnosis.
