Core Tip

Core Tip: Schistosomiasis still poses significant morbidity to individuals, especially those in endemic areas. Its variable clinical presentation, protracted course, and nonspecific endoscopic findings frequently lead to erroneous diagnoses. Having a high index of clinical suspicion, actively inquiring about exposure or travel history, utilizing epidemiologic surveys to understand disease distribution, correlating symptoms with basic laboratory tests (especially eosinophil count), and obtaining histopathologic examination of colonic mucosa are essential in making a conclusive diagnosis. Confirming the diagnosis is important, as colonic schistosomiasis can be effectively treated with anthelminthic therapy (praziquantel) obviating the need for unnecessary medical treatments and invasive surgical procedures.
