Tubal schistosomiasis as a cause of ectopic pregnancy in endemic areas?; a report of three cases.

Tubal schistosomiasis as a cause of ectopic pregnancy is uncommon. We are reporting three cases of tubal pregnancies in which the histopathological examination showed a bilharzial disease of the tube. Schistosomiasis to Schistosoma haematobium occurs in Gabon with an incidence of 8% to 44% of the adult population, and schistosoma ova have been found in 2.5% of histopathological examinations in removal of any genital tissue. Even if schistosomiasis was not the main causative agent of infertility, in this population which has the lowest fertility index in subsaharan Africa, it might impair an already altered tubal function by salpingitis. We suggest that parasitic examination should be made as a part of the management program of infertility and after an ectopic pregnancy in endemic areas.
