Are there any other possible causes of an itchy skin rash that resembles hives? (photo)

Doctor's Answers 1

Hives, also known as urticaria, presents with a rash that is itchy and often appears like a giant mosquito bite. Typical hives do usually appear and settle within minutes to hours. The appearance of hives is not specific, and there are a number of skin disorders that can also mimic hives.

Conditions such as urticarial vasculitis and urticarial dermatitis can also present like hives, as can some viral induced rashes. However, these rashes usually last for more than 24 hours.

Typical hives or urticaria generally respond well to antihistamines. If the rashes are persistent, it would be a good idea to see your dermatologist or doctor to get it further evaluated and treated.

Sorry to hear that your child has developed hives after an episode of viral illness. I agree with Dr Colin Theng that a viral infection is most likely the trigger for this episode and antihistamines such as cetirizine would be the mainstay of treatment. I would usually optimise the dose of antihistamines for good control. If the maximum dose is still not able to control your child's hives, then a course of prednisolone may need to be considered. These medicines will help to switch off the activity of mast cells which have gone into overdrive, causing the appearance of hives.

Do I need to see a dermatologist for an itchy skin rash from cold weather?

It is not uncommon to develop dryness and itch after a trip to a cold country with low humidity. The dryness of the skin can aggravate the itch and can lead to the development of eczema. Hives can also be triggered by the change in temperature and climate. It would be useful for you now to use soap free washes and moisturize the skin regularly but if the dryness and scaling is persistent, you can visit the dermatologist who will be able help you with this problem. Hope you had an enjoyable trip to Europe!
