What skin disorder is characterized by the presence of blisters and severe itching?

The skin disorder characterized by the presence of blisters and severe itching is commonly known as contact dermatitis. This condition occurs when the skin comes into contact with an irritant or an allergen, leading to an inflammatory response. The blisters can form as a reaction to substances such as certain chemicals, plants, or metals, and the intense itching is a hallmark symptom, prompting individuals to scratch the affected area.

Contact dermatitis typically manifests as red, inflamed skin with blisters that may weep or ooze, especially if scratched. The blisters may crust over and eventually heal, but the presence of itching can often be bothersome and lead to further skin irritation. This condition emphasizes the allergic reaction aspect of skin disorders, distinguishing it from other types such as psoriasis, which is primarily characterized by scaly patches, or eczema, which involves inflammation and can result in dry, cracked skin rather than blister formation. Urticaria, while also causing itching and welts, is usually associated with hives rather than blisters specific to contact with irritants. Thus, contact dermatitis is the most accurate choice for a disorder marked by both blisters and severe itching.
