Management of Pediatric Appendiceal Carcinoid Tumor: A Single-center Experience

RESULTS Eight (0.94%) out of 843 children who underwent appendectomy during the study period were detected with histological evidence of ACT and were included in the study. Median tumor size was 0.35 (range, 0.1-1) cm. The tumor had invaded the muscularis propria in 4 (50%), the submucosa in 2 (25%), the subserosa in 1 (12.5%), and the mesoappendix in 1 (12.5%) patient. All the patients had tumor-free margins and none of them had lymphadenopathy at diagnosis. Mitotic index and Ki67 levels were >2 in two patients. Only appendectomy was performed in all patients. No recurrence was observed in any patient throughout the follow-up period. Patients were followed up for a mean±SD; 41.2±11.1 months.
