The patient treated schistosomiasis twice without effects. During physical examination and complementary exams, she presented ecchymosis in the midline of the abdomen, normal platelet level, giant hematoma in the rectus abdominais muscle without periportal changes. A careful retrospective analysis shows inconsistency between the initial platelet levels and the severe progression of the clinical. The investigation and confirmation of thrombocytopenia is very important, and some medical center recommend manual counting through blood smears. Prospective studies are needed to know how platelet measurements should be performed in schistosomiasis.Keywords: Schistosomiasis mansoni, rectus abdominis, platelet function tests, shock, hemorrhagic
