Acute appendicitis bij een slijmbekercelcarcinoïd

A 43-year-old man presented at the emergency room with continuous right lower quadrant abdominal pain. The pain started the previous day. Physical and laboratory examination indicated acute appendicitis. The patient underwent an appendicectomy of the inflamed appendix with periappendicular infiltrate. However, histological examination revealed a small goblet cell carcinoid, histological group C, with acute inflammation. The patient then underwent laparoscopic right hemicolectomy. Several tumour cells were present in a lymph duct at the appendix base. Without histological examination such a rare diagnosis can easily be missed. The treatment should be based also on the histological classification.
