The cellular features of adeno‐endocrine‐cell carcinoma of appendiceal origin are presented. The pleural fluid contained metastatic predominantly atypical cells in linear cluster accompanied by numerous mesothelial cells. The cells had small round nuclei, with a slight tendency to molding; nucleoli were absent. The cytologic findings in Papanicolaou‐stained smears of the pleural fluid suggested a metastatic small‐cell carcinoma of the lung. Subsequently, adeno‐endocrine‐cell carcinoma of the appendix was demonstrated at autopsy. Reports of such occurrences are few; no study, to the best of our knowledge, has previously documented the cytologic diagnosis in pleural fluid. Diagn.
