Port-site metastasis after explorative laparoscopy for an incidental appendiceal mucinous cystadenocarcinoma detected with FDG PET/CT

Abstract

A 62-year old female with a history of appendix carcinoma came to our department for an 18 F FDG PET/CT to further characterize a subcutaneous fixed small mass in the right fosse detected at clinical examination. Fourteen months earlier, she had undergone a right hemicolectomy because of an appendiceal mucinous cystadenocarcinoma. Since the diagnosis of appendicitis was presumed before she went into surgery, an explorative laparoscopy was performed. An inflammatory mass with loss of all anatomical references was found; hence the laparoscopy was reverted to a laparotomy.
