Unusual appendiceal pathology presenting as urologic disease

Abstract

We report on 3 cases of unusual appendiceal pathology presenting as urologic disease: 2 cases were benign mucoceles and 1 a malignant mucocele or cystadenocarcinoma of the appendix. Two cases presented as pelvic masses causing urinary frequency and the third with fever and hydronephrosis. The appendix must remain in the differential diagnosis for both acute and chronic disease processes.
