Papular urticaria, usually called hives, is characterized by large numbers of very itchy red bumps (papules) that come and go every few days over a period of a month or so. The bumps are usually between 0.2 and 2 cm. in size and some may develop into fluid-filled blisters (bullae). This condition is usually triggered by allergic reactions to insect bites, sensitivity to drugs, or other environmental causes. In some cases, swelling of the soft tissues of the face, neck, and hands (angioedema) may also occur.
Because it is difficult for children and adults to resist scratching these itchy crusted bumps, the possibility of infection is great and caution must be taken. Papular urticaria may accompany, or even be the first symptom of various viral infections including hepatitis, infectious mononucleosis, or German measles (rubella). Some acute reactions are unexplained, even when recurrent.
