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.

HighlightsPrimary lymphomas of appendix are extremely rare tumors. The incidence is 0.015% of all gastrointestinal lymphomas.The neoplasms of appendix usually manifest clinically with sign and symptoms of acute appendicitis.Preoperative diagnosis is difficult and often occurs through histopathological examination, so it is mandatory for all appendectomies.There are no clear guidelines for therapy. Primary surgical resection followed by post-operative chemotherapy showed high efficacy.

Primary appendiceal neoplasms are uncommon, being found in approximately 0.5%-1.0% of appendectomy specimens at pathologic evaluation. Primary appendiceal Burkitt's lymphomas are rare occurring in 0.015% of all gastrointestinal lymphomas. Almost all reported cases of appendiceal lymphoma have proved to be non-Hodgkin lymphoma. The majority of appendiceal lymphomas are of B-cell. Patients were almost entirely males. Acute appendicitis is the most common clinical manifestation. This report describes a rare case of primary appendiceal lymphoma in a patient presented with hematuria and dull aching right lower abdominal and back pain.
