Schistosoma mansoni: a rare cause of tubal infection

S. haematobium is an important cause of urinary schistosomiasis, and symptomatic female genital infection is a common gynecological finding in areas where S. haematobium is prevalent. On the other hand, genital manifestations of intestinal schistosomas as S. mansoni are not frequent or are misdiagnosed. A case of a 40-year-old woman with abnormal uterine bleeding and asymptomatic tubal infection by S. mansoni identified in histological examination is presented.

Genital schistosomiasis mansoni: tubal tumor and parietal peritoneum involvement diagnosed during laparoscopy / Esquistossomose mansônica genital: tumor de trompa e envolvimento do peritônio parietal diagnosticados durante laparoscopia

Female genital schistosomiasis is not uncommon in endemic areas for schistosomiasis, but there are few reports in the Brazilian medical literature. Here, we describe the case of a 31-year-old woman with lower abdominal pain who was diagnosed as presenting a fallopian tube tumor caused by Manson's schistosomiasis. The diagnosis was delayed because her symptoms were considered nonspecific. Involvement of the parietal peritoneum of the ovarian fossa was observed during laparoscopy and confirmed by histological analysis. The left tube and the tumor were excised and schistosomiasis was treated with praziquantel. She presented a full recovery and options for future reproduction are under evaluation.

Esquistossomose genital feminina não é incomum em áreas endêmicas para esquistossomose, mas, há poucos relatos na literatura médica brasileira. Descrevemos aqui, o caso de uma paciente de 31 anos com dor abdominal no baixo ventre que recebeu o diagnóstico de tumor da trompa de falópio causada pela esquistossomose mansônica. O diagnóstico foi retardado porque os sintomas foram considerados inespecíficos. Havia envolvimento do peritônio parietal da fossa ovárica durante a laparoscopia, confirmado à histologia. A tuba esquerda e o tumor foram extirpados e a esquistossomose foi tratada com praziquantel. A paciente apresentou recuperação completa e opções para reprodução futura estão sob avaliação.
