Abstract
A retrospective study of the histopathological findings of more than 11,443 appendices submitted as surgical specimens over 14 years was performed in this department. In most cases routine histopathological examination added little clinically important information to other clinical and operative gross findings, but a variety of interesting and uncommon lesions were identified. In 85 cases clinically important pathological findings were first discovered on routine histopathological examination. These included enterobiasis, schistosomiasis, mucocele, trichuriasis, tuberculosis, ascariasis, endometriosis, mucinous cystadenoma, granuloma, carcinoid tumour, neuroma, clonorchiasis, primary adenocarcinoma and secondary carcinoma.
