[A Case of Appendiceal Goblet Cell Carcinoma].

A 72-year-old man complained of right lower abdominal pain. A CT scan showed an acute appendicitis. Laparoscopic appendectomy was performed. Histopathological examination of the resected specimen identified goblet cell adenocarcinoma(GCA), predominantly extending through the muscularis propria of the appendix. The tumor invaded into the serosal tissue. Subsequently, robotic-assisted ileocecal resection with D3 lymphadenectomy was performed. The final pathological diagnosis was GCA(pT3N0M0, pStage ⅡA). GCA of the appendix is a rare entity that exhibits characteristics of both carcinoid and adenocarcinoma. We report this as a relatively rare and significant case, accompanied by a review of relevant literatures.
