Urticaria

John L. Bezzant,M.D.

This patient has developed rather severe urticaria, the cause of which was unknown. In urticaria, the skin swells and initially looks red and later can blanch as the amount of fluid increases within the skin. Internal organs can be involved in the process, and we are particularly concerned about the respiratory and cardiovascular system in this process.
