![]() Conclusions: the longitudinal method of studying the cecal appendix allows a better recognition of many lessions that might otherwise be overlooked. The CHPR cases had less normals and early lesions than the private place, as well as more cases with periappendicitis. 21 cases of carcinoid tumors were found most of them located at the middle third of the organ, with a median size of 7 mm almost all the cases had concomitant appendicitis and most of the patients were adolescent females. Parasites (mainly enterobius vermicularis) where found in 7% of the cases studied in the late years. 7 cases were fibrous obliteration of the lumen. 11 cases were undetermined granulomatous appendicitis. 1.519 were normal specimens 1.317 were early appendicitis 502 were diffuse appendicitis without priappendiceal inflammation and finally 7.047 were appendicitis with transmural inflammation and periappendicitis. Results: a total number of 10.424 cecal appendices were gathered 6705 from CHPR and 3.719 from the private laboratory. The specimens were longitudinally sectioned after formalin fixation and the whole longitudinal cut surface was embedded for histological examination. Methods: all cecal appendices were studied by the authors and the same method was applied. 2) To compare the results in both places. Objectives: 1)To review the pathologic findings in pediatric cecal appendix specimens studied in a 20 years period (1983-2003) at the Pereira Rossell Hospital (CHPR) and also at a private laboratory in the same period.
