摘　　要：BACKGROUND Schistosomiasis is a chronic parasitic infection endemic in many countries.Colonic schistosomiasis is a rare entity with no specific clinical manifestations or endoscopic aspects,which delays the diagnosis.Diagnosis is primarily dependent on histopathological analysis,and treatment with antihelminthics typically resolves the infection.CASE SUMMARY We present the case of a 21-year-old male who suffered from chronic diarrhea and abdominal pain.Physical examination found no abnormalities,blood tests were normal,and stool examination was negative.A colonoscopy revealed a nodular terminal ileal mucosa,two cecal polypoid lesions with no particular surface pattern,and millimetric erosions in the rectum.The presence of Schistosoma eggs with thick peripheral capsules and viable embryos inside and numerous eosinophils surrounding the egg capsule were observed on histopathological examination.The patient received praziquantel,and his symptoms were resolved.CONCLUSION Colonic schistosomiasis should be considered as a differential diagnosis,especially in endemic countries.Endoscopy and histopathological examination can confirm the diagnosis,and antihelminthics are an effective treatment.
