Adenocarcinoma. This case has typical features for carcinoma: so-called tissue fragments and community border. Although mesothelioma comes into the differentiation whenever you have adeno in pleural fluid, but mesothelioma is so so rare. Also mesothelioma has a spectrum of atypical cells, adeno has "dual populations": a population of benign/reactive mesothelial cells and a population of foreign tumor cells. Also, mesothelioma still maintains some mesothelial cell features such as windows between cells, which is not apparent in this case.
