The patient reported dyspnoea and that his whole body was affected by hives, blistering and irritation.  Dermatologic and allergy consultation was performed. Chest X ray and laboratory results were solicited, but results are not available at this moment. Treatment with antihistamines and glucocorticoids (local and systemics) was prescribed.
