trematode, Schistosoma spp, and affects many systems in the body including the
gastrointestinal tract. Schistosomiasis of the appendix is a well-recognized disease and
presents as a chronic granulomatous inflammation. This study aims to document the

Background: Schistosomiasis is one of the neglected tropical diseases caused by a trematode, Schistosoma spp, and affects many systems in the body including the gastrointestinal tract. Schistosomiasis of the appendix is a well-recognized disease and presents as a chronic granulomatous inflammation. This study aims to document the frequency and pattern of distribution of schistosomal appendicitis in our environment.
Materials and Methods: This is a retrospective histopathological review of schistosomiasis of the appendix in the Department of Pathology, Ahmadu Bello University Teaching Hospital, Zaria - Nigeria, between January 1, 1991 to December 31, 2012.
Results: Within the study period, there were 1,464 appendectomy specimens histologically examined in the Pathology Laboratory. Thirty of these, representing 2.1%, were diagnosed as schistosomiasis of the appendix. The male:female ratio was 6.5:1 and peak age incidence was in the 20-29 years age group. Abdominal pains, vomiting and fever were seen in 23 (76.7%) and altered bowel motion in seven (23.3%) patients.
Conclusion: This study showed that schistosomiasis of the appendix is not rare and that its presentation is similar to other forms of appendicitis. There is a need to focus on the prevention of schistosomiasis in order to reduce morbidity among these economically viable age groups.
