There are two main forms of contact dermatitis – irritant and allergic. One can develop irritant contact dermatitis after repeated exposure to skin irritants such as detergents and harsh soaps.
On the other hand, allergic contact dermatitis occurs in people who have an allergy to specific substances. The common allergen sources include poison ivy, oak, and sumac. Some people are allergic to chemical substances in hand lotions, building materials, hand gloves, etc.
The symptoms of eczema vary depending on factors such as types, patterns of symptoms, specific areas affected and whether the eczema types are short-term or long-term among other things.
Nummular or discoid eczema
This type of eczema normally occurs in adults. It is related to atopic eczema whose occurrence points out to the tendency in inheritance. Individuals with allergic asthma, hay fever, or food allergies are commonly affected by nummular eczema. Even though, dry skin, irritants and changes in temperature can contribute to its development.

Acrodermatitis is a rare childhood skin condition. It can start as early as 1 month to 10, 12 or so years. Dermatologists don’t know the causes of acrodermatitis.

How do you get hints or if your child is suffering from acrodermatitis? Red spots that cause itching usually start from the legs in a few days (4 days or so). As the eruption proceed s to the upper body areas (the buttocks, trunk, chest, arms, and face), the red spots begin to form purplish blisters that also itch.
Other symptoms include:
- Pink-brown or copper-colored papules on forearms, buttocks, and legs (with a firm feeling)
This is one of the conditions responsible for skin rashes that itch and spread to the rest of the major body areas. If symptoms of acrodermatitis last for more than 4 months it can become chronic especially if it occurs after the first eruption has healed.
