Patient's question:
My neighbor's baby has purpura. I want to know what symptoms are associated with purpura?Doctor's answer:
Allergic purpura is a microvascular allergic hemorrhagic disease. It is characterized by skin petechiae, commonly appearing around the joints of the lower limbs and buttocks, with symmetrical distribution, appearing in batches, varying in size, and differing in color depth. They can merge into patches and generally subside gradually within a few days, but may recur. Patients may also experience gastrointestinal symptoms. The causes of allergic purpura include infections, food allergies, drug allergies, pollen, insect bites, and other allergies. However, the allergic cause is often difficult to determine, and it is more common in children and adolescents.
