DIC, unlikely: PT/PTT normal; wouldn't just see gum bleeding
hypersplenism: would cause anemia
iron deficiency: anemia
vitamin C deficiency: wouldn't cause thrombocytopenia
von Willebrand disease: mixed platelet/coagulation disorder → would cause deep joint bleeding instead of mucosal membrane bleeding. Inherited (Autosomal Dominant), would see symptoms before. PTT can be normal/high.

The hallmark of ITP is isolated thrombocytopenia.
