الإجابة: B. Immune Thrombocytopenic Purpura (ITP)
Petechiae and bruising with thrombocytopenia, no schistocytes, no fever or neurological signs, no organomegaly and a normal WBC point to ITP. ITP is a diagnosis of exclusion; the low Hb can be explained by bleeding.
- TTP and HUS are microangiopathies with schistocytes (plus neurological features in TTP, renal failure in HUS).
- DIC occurs in an acutely ill patient (sepsis, trauma) with a coagulopathy.
