[Two Cases of Appendiceal Goblet Cell Adenocarcinoma Diagnosed after Appendectomy]

Case 1:A 69-year-old man. He was diagnosed with abscess-forming appendicitis and initially managed conservatively, followed by a laparoscopic appendectomy. Histopathological examination revealed goblet cell adenocarcinoma(GCA)of the appendix. A subsequent laparoscopic-assisted ileocecal resection with D3 lymph node dissection was performed. The pathological findings were V, pT3(subserosa), GCA, INF b, BD2, Ly0, V0, Pn1a, pN0, cM0, pPM0, pDM0, pRM0, and pStage ⅡA. Case 2:A 29-year-old man. He underwent a laparoscopic appendectomy for a diagnosis of acute appendicitis. Histopathological analysis revealed GCA of the appendix. A laparoscopic-assisted ileocecal resection with D3 lymph node dissection was subsequently performed. The pathological findings were V, pT3(subserosa), GCA, INF c, BD1, Ly0, V0, Pn0, pN0, cM0, pPM0, pDM0, pRM0, and pStage ⅡA. These cases are reported with a review of the relevant literature.
