Final answer:
Idiopathic thrombocytopenic purpura (ITP) is a type III hypersensitivity disorder characterized by the formation of immune complexes and their deposition in tissues and blood vessels. Manifestations of ITP include purpura, petechiae, easy bleeding or bruising, and prolonged bleeding from cuts or injuries.
Step-by-step explanation:
Idiopathic thrombocytopenic purpura (ITP) is a type III hypersensitivity disorder characterized by the formation of immune complexes and their deposition in tissues and blood vessels. In ITP, the immune system mistakenly targets and destroys platelets, leading to low platelet levels in the blood. Manifestations of ITP include purpura (bruising), petechiae (small red spots on the skin), easy bleeding or bruising, and prolonged bleeding from cuts or injuries.
