Schistosomal appendicitis in pregnancy.Swiss Surg. 2002;8(3):121-2.

Acute appendicitis is the most common acute surgical infection during pregnancy. Although usually pyogenic in origin, parasitic infections account for a small percentage of cases. Despite the relatively high prevalence of acute appendicitis in our environment, it is not commonly associated with schistosomiasis. We report here the association of pregnancy and appendicitis caused by Schistosoma haematobium. Schistosomiasis is very common complication of pregnancy in hyperendemic areas. Schistosome egg masses can lodge throughout the body and cause acute inflammation of the appendix, liver and spleen. Congestion of pelvic vessels during pregnancy facilitates passage of eggs into the villi and intervillous spaces, causing an inflammatory reaction. Tourism and immigration make this disease a potential challenge for practitioners everywhere.

Schistosomiasis presenting as acute appendicitis in a traveler. J Travel Med. 1998 Sep;5(3):147-8.

Schistosomiasis, a waterborne trematode infestation, is one of the most widespread parasitic diseases in the world. It occurs in well-defined endemic geographical areas. Schistosomiasis of the appendix was first described by Turner in 1909, and has been reported from endemic areas. However, appendicular schistosomiasis in travelers has not been reported in the English literature. We describe an Israeli traveler with acute appendicitis as the presenting symptom of schistosomiasis, 2 years after a visit to Africa.
