Pseudomesotheliomatous adenocarcinoma spreads within the pleural space. Owing to frequent invasion of chest wall, diaphragm, or mediastinal pleura, patients present at a primary tumor classification of T3. Those with malignant pleural effusion are classed as T4. Patients usually present with advanced disease of stage IIIB or IV. [46] Metastases from pseudomesotheliomatous adenocarcinoma have a distribution that is similar to those of metastatic lung carcinoma in general, with frequent metastatic sites being adrenal glands, lymph nodes, liver, and brain.
