Histopathological findings in appendectomy specimens: a retrospective clinicopathological analysis.

The prevalence and clinical features of the various obstructive lesions in appendectomy specimens studied pathologically with special emphasis on unusualetiological findings were evaluated. The clinic-pathological data of 251 patients who underwent appendectomies for presumed acute appendicitis from January; 2008 to December; 2010; were reviewed retrospectively. Among all appendectomies performed, eleven (4.38%) specimens revealed incidental abnormal pathological diagnoses: Four cases (1.59%) of Enterobiusvermicularis, Ascaris lumbricoides two cases (0.79 %), schistosomiasis eggs in three cases (1.19%), and parasitic amebiasis in two cases (0.79%). None suffered tumor in any appendectomies specimens. Mean age was lower, perforated and gangrenous appendicitis was absent and negative appendectomy rate was higher in patients with unusual appendix pathology.
