Schistosomiasis or bilharzia is a parasitic disease found in tropical countries. Most infections are subclinical but may progress to chronic form characterized most frequently by the presence of liver involvement and portal hypertension. We report a patient that presented chronic polyarthritis with positive rheumatoid factor. During investigation, increased liver enzymes, negative hepatitis serologies and signs of portal hypertension on an ultrasound examination raised suspicion of S. mansoni infection. We will discuss pathophysiology and clinical manifestations of S. mansoni infection with special attention to articular involvement.
血吸虫病或血丝虫病是一种在热带国家发现的寄生虫病。大多数感染是无症状的，但可能会进展为慢性形式，其特征通常是存在肝脏受累和门脉高压。我们报告了一例表现为慢性多发性关节炎且类风湿因子阳性的患者。在检查过程中，肝酶升高、肝炎血清学阴性和超声检查有门脉高压的迹象，引起了对曼氏血吸虫感染的怀疑。我们将讨论曼氏血吸虫感染的病理生理学和临床表现，特别注意关节受累。
