What is the medical term for a hereditary rash of the skin?

1. Contact dermatitis

2. Atopic dermatitis

3. Psoriasis

4. Eczema

The correct answer is: Atopic dermatitis

The medical term for a hereditary rash of the skin is atopic dermatitis. This condition is characterized by chronic inflammation and is often associated with a family history of allergies or asthma. It typically manifests as itchy, red, and inflamed skin, which can occur in various locations on the body. Atopic dermatitis is commonly seen in children but can persist into adulthood. This condition is distinct because it involves a genetic predisposition, as it frequently occurs in individuals with a family history of similar allergic conditions. While eczema is often used interchangeably with atopic dermatitis, it can also refer to a broader range of skin conditions that cause irritation and inflammation. However, atopic dermatitis specifically highlights the hereditary and atopic (related to allergies) aspect of the rash. Other options such as contact dermatitis pertain to skin reactions due to external irritants or allergens rather than a hereditary condition. Psoriasis, while it can have a genetic component and caused by an immune system issue, is characterized by raised, silvery scales rather than a hereditary rash per se.
