طفل عمره ٤ سنوات قبل أسبوعين كان عنده زكام، والآن ظهرت نقاط حمراء صغيرة على ساقيه وكدمات، ونزيف خفيف من الأنف. يلعب بشكل طبيعي. الصفائح ١٥ ألفاً، والهيموغلوبين وكريات البيض طبيعية. ما الأرجح؟

A 4-year-old had a cold two weeks ago and now has small red spots on the legs, bruises and a mild nosebleed. He is playing normally. Platelets 15,000, with normal Hb and white cells. What is most likely?

1. Haemophilia
2. Acute leukaemia
3. Disseminated intravascular coagulation
4. Immune thrombocytopenia

Answer: D) Immune thrombocytopenia. Isolated thrombocytopenia after a viral illness in a well child indicates ITP, which usually resolves within weeks; a normal Hb and white count make leukaemia less likely.
