Background: Vermiform appendix, although a rudimentary structure in humans is one of the frequently encountered specimens in the routine drill of a histopathologist. Acute appendicitis is the most rampant diagnosis that frequently demands an emergency procedure. However, grossly normal- appearing appendix, removed from patients with suspected acute appendicitis, on histopathological examination may harbour a more serious underlying pathology. Therefore it is rationale to examine all the operated specimens.

On the other hand literature shows that appendicitis can be associated with peripheral blood eosinophilia, thereby necessitating complete hemogram, prior to preparation of the patient.

Aims and Objectives

1. To study the histomorphology of appendicitis specimens with special interest to unusual presentations.
2. To correlate peripheral blood eosinophilic count in cases of subacute appendicitis.

Materials and Methods: This study was conducted with appendicectomy specimens received to the Department of Histopathology MMC &RI from K.R. hospital. A total of 125 cases were included in the present study that were clinically suspected to be acute or recurrent appendicitis.

Results: In this descriptive study, the records pertaining to 125 appendicectomy specimens, at our tertiary care centre were studied and compared with the available data.

Conclusion:  It is of utmost importance to examine all the appendicectomy specimens so as to not miss on any unusual or coexisting pathology.
