Unusual Histopathological Findings in Childhood Appendectomy Specimens.

Abstract

The purpose of this study was to find the unusual findings in the childhood appendectomy specimens and their incidence. The clinicopathological data of 1,306 patients whose ages ranged from 3 to 16 were retrospectively collected. Histopathological findings in appendectomy specimens taken from patients who had a prediagnosis of appendicitis were obtained. Incidental appendectomies were not included in the research. Unusual findings were reevaluated in the histopathological assessment of appendectomy specimens. The number of patients whose pathological findings are considered unusual is 25 (1.91%). Nine of the patients were girls and 16 of them were boys. Their ages ranged from 6 to 15. Pathological results revealed that there were 16 (1.22%) cases of parasitosis, 3 (0.23%) cases of granulomatosis, 3 (0.23%) cases of eosinophilic appendicitis, 2 (0.15%) cases of carcinoid tumors, and 1 (0.08%) case of appendiceal non-Hodgkin's lymphoma. All patients underwent a standard appendectomy. Uncommon histopathological findings in childhood appendectomy specimens are more common than those in adulthood. This kind of certain unexpected lesions of the appendix may require advanced diagnostics, careful clinical care, follow-up for years, and a multidisciplinary approach. Therefore, histopathological examinations of appendectomy specimens must be performed routinely.
