Schistosomiasis of the female genital tract: a two-center study

Schistosomiasis (also known as bilharziosis) is a parasitic infection still endemic in Madagascar. Its transmission is perpetuated by population lifestyles in tropical countries. A genital location is relatively rare; diagnosis is histological. This is a retrospective, descriptive study of genital schistosomiasis observed in the anatomic pathology laboratory of Sampan'asa luteriana ho an'ny fahasalamana and the Joseph Ravoahangy Andrianavalona University Hospital Center over the 6-year period from January 2010 through December 2015. We collected 13 cases. The mean age of the patients was 31.6 years and ranged from 4 to 48 years. Localization was cervical (n = 10), tubo-ovarian (n = 2), and vulvar (n = 1). Clinical signs were isolated bleeding or associated with other signs for cervical localization, suspicion of cyst for the vulva, and suspicion of mass for the ovary. The diagnosis was based on the presence of schistosome eggs in all cases, associated with tuberculoid granulomas (n = 9), eosinophilic polynuclear cells (n = 1), and giant cells (n = 2). We observed one case of squamous cell carcinoma that developed on cervical schistosomiasis. Schistosomiasis is a neglected tropical diseases. Malignant transformation is possible. A cervical hemorrhage is not synonymous with cancer but may reveal a specific inflammatory lesion. Histological examination is necessary for diagnosis.
