腹腔鏡下虫垂切除術を施行した虫垂杯細胞型カルチノイドの１例

抄録

A 57-year-old man was admitted to our hospital because of right lower abdominal pain. He was diagnosed as having acute appendicitis, and underwent laparoscopic appendectomy. However, the histopathological diagnosis was goblet cell carcinoid of the appendix. Since the surgical margin and lymph vascular invasion were negative, and metastasis was not observed in lymph nodes, additional surgery and postoperative adjuvant chemotherapy were not performed. There have been no signs of recurrence as of 1 year after the operation.
Goblet cell carcinoid of the appendix is rare, and only 118 cases including our case have been reported in the Japanese literature. Goblet cell carcinoid is known to be almost as malignant as adenocarcinoma, and no therapeutic guidelines or clear notion of the prognosis have been established as yet. Herein, we report a case of goblet cell carcinoid of the appendix removed by a laparoscopic appendectomy together with a review of the literature.
