Abstract
Case 1 involved a 51-year-old man who underwent appendectomy with a diagnosis of acute appendicitis. The postoperative histological diagnosis was goblet cell carcinoid (GCC). Laparoscopic ileocecal excision was performed. Case 2 involved a 43-year-old woman who underwent simple abdominal hysterectomy + bilateral salpingo-oophorectomy with a suspicion of bilateral malignant ovarian tumors. During the operation, a swollen appendix was detected and it was simultaneously resected. The postoperative histological diagnosis was GCC of the appendix and ovarian metastasis. Right hemicolectomy was performed. Case 3 involved a 73-year-old man who underwent appendectomy with a diagnosis of acute appendicitis. The postoperative histological diagnosis was GCC. An abdominal CT scan undertaken after the operation revealed a nodular lesion which had oppressed the rectum. Accordingly ileocecal excision + Hartmann operation were performed.
GCC is classified into a subtype of adenocarcinoma and has a high grade of malignant potential. The preoperative diagnosis is difficult and we have to consider some additional therapy. As we recently experienced three cases of GCC diagnosed after appendectomy and performed reoperation, these cases are presented here with a review of the literature.
