Cytology of metastatic appendiceal goblet cell carcinoid in pleural effusion fluid: a case report.

Goblet cell appendiceal carcinoid (GCAC) is a rare neoplasm. We described the case of a 72-year-old man who presented with symptoms related to ascites. A computed tomography (CT) scan showed a mass involving the base of the appendix, ascites and concomitant pleural effusion. Thoracentesis of the pleural fluid showed metastatic GCAC. The appendiceal mass was biopsied and diagnosed as a GCAC. We describe the cytologic features of the metastatic GCAC to pleural fluid. To our knowledge this is the first such described case.
