Hive is a common affliction and its symptoms include papules and light pink oedematous plaques, highly pruritic that are sometimes accompanied by angioedema. Some triggering factors are: medicine, food, insect stings, infections, especially when it comes to acute hive. In chronic hive although, in most of the cases, the underlying cause remains unknown.
The lesions this affliction causes are raised, highly pruritic and sometimes have a pale centre. Angioedema manifests through oedema located in the face area, on the eyelids, lips, hands, genitals and it is more painful than it is itchy. Acute hive has a short evolution time, for up to 1-2 weeks and the chronic hive evolves over a 6-week period of time and sometimes up to a couple of years.
The diagnosis is based on the clinical exam executed by the dermatologist and the patient’s medical history and the laboratory testing is usually recommended in chronic cases. Cutaneous testing for the food allergy and medicine is recommended if the suspicion of an allergy as the cause of the acute hive exists.
The treatment is based on avoiding the triggering factors (when they are successfully identified) along with drug therapy such as antihistamines, steroids, and leukotriene inhibitor.
