Blood film says it all! Rare case of congenital TTP misdiagnosed as ITP

We report a case of a 16-year-old female who presented with bleeding diathesis. Peripheral blood film examination was consistent with microangiopathic hemolytic anemia with 7% fragmented red blood cells. The ADAMTS13 level was 40 ng/ml (reference range: 630–850 ng/ml). She responded to plasma exchange therapy and methylprednisolone and was discharged in a stable condition.
