 Clinicopathological study on 2,169 appendices surgically resected was carried out. Out of 2,169 cases, 1,943 cases were clinically diagnosed as acute and/or subacute appendicitis and were pathohistologically divided into six groups; i) cases without remarkable change of the appendix (group 1) (444 cases, 22.9%), ii) cases with minimal change in acute appendicitis (group 2) (727 cases, 3 7.4%), iii) cases with acute phlegmonous appendicitis (group 3) (649 cases, 33.4%), iv) cases with acute gangrenous appendicitis (group 4) (73 cases, 3.8%), v) cases with subacute appendicitis (group 5) (4 cases, 0.2%), vi) cases with chronic appendicitis (group 6) (46 cases, 2.7%).

 Mean white blood cell (WBC) count in these six groups was 10,613.2, 10,265.8, 15,170.5, 16,331.9, 8,875.0, 12,286.5/mm3, respectively. The difference in the mean WBC count between groups 1, 2 and groups 3, 4, as well as between group 6 and groups 3, 4, was statistically significant (p<0.005).

 In 55 cases out of 2,169 cases, associated and/or incidental lesions were microscopically discovered including diverticular disease (16), argentaffin carcinoid (9) and goblet-cell carcinoid (1), epithelioid cell granuloma (9), focal necrotizing arteritis (8), Schistosomiasis japonica (5), simple mucocele (4), mucinous cystadenoma (1), metaplastic polyp (1) and cavernous hemangioma (1).

 According to the results thus obtained, brief discussion was made on the discrepancy between clinical diagnosis and pathologic diagnosis and on correlation of WBC count and pathologic diagnosis in cases clinically diagnosed as acute and/or subacute appendicitis, and also on associated and/or incidental lesions.
