Abstract:
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.

Appendicitis-I: Introduction
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
