title: Carcinoid tumors of the appendix in children.
abstract: We report ten cases of carcinoid tumor of the appendix observed in children from 1988 to 1996. The patients included six females and four males with an average age of 13 years at presentation. They were admitted after complaining of pain in the lower abdominal quadrant. In eight children who presented with symptoms of acute appendicitis, the tumor was located at the tip of the appendix. Diagnosis was performed after appendicectomy (AE) and pathologic examination, which revealed a tumor slightly under 1 cm in size. Two other children were admitted with clinical signs of peritonitis due to larger tumors measuring more than 2 cm on the base of the appendix. One patient underwent a cecectomy, the other a right hemicolectomy. For all patients follow-up was 3 years, and all recovered fully. According to these findings and a review of the literature, we suggest conservative surgical procedures in children. More than 70% of these tumors are localized at the tip of the appendix and represent an incidental pathologic finding during AE; AE alone is curative. Patients with a bulky tumor of the appendicular base measuring 2 cm and invading the serosa and mesoappendix without metastases may be treated with a cecectomy; ileocecal resection may be indicated in cases where the tumor has infiltrated tissue beyond the cecum with localized metastases and in patients with incomplete gross resection. Right hemicolectomy is questionable in this age group and restricted to rare conditions.
