Allergic purpura, also called hemorrhagic capillary toxicosis, is an allergic reaction of the body's small arteries and capillaries to certain substances, increasing vascular permeability and producing exudative bleeding and edema. The allergens may be bacterial, viral, or parasitic infections; drugs such as antibiotics or sulfonamides; or foods such as plant pollen, fish, shrimp, eggs, or milk. The main clinical manifestation is bleeding spots on the skin, most often around the joints of the lower limbs and on the buttocks; there may also be paroxysmal abdominal colic or persistent dull pain, often with vomiting, diarrhea, and bloody stools; joints such as the knees and wrists may show swelling, warmth, and effusion; kidney involvement may cause hematuria, proteinuria, and casts in the urine; and lesions in the brain or cerebral vessels may cause headache, blurred vision, convulsions, and paralysis.
