Which disorder is a child with atopic dermatitis at risk of developing in the future?

A child with atopic dermatitis is at increased risk of developing asthma in the future due to the concept of the "atopic march." Atopic dermatitis is often one of the first manifestations of atopy, a genetic predisposition to allergic conditions, which may include asthma and allergic rhinitis. Research indicates that children with a history of atopic dermatitis are more likely to develop asthma as they grow older, making the association significant in the context of allergic disease progression. This connection is thought to be influenced by both genetic factors and environmental exposures that can trigger inflammatory responses associated with these conditions.

The other options listed do not have that same direct or common progression associated with atopic dermatitis. While tinea pedis is a fungal infection and systemic lupus erythematosus is an autoimmune disorder, they do not follow the atopic pathway associated with conditions that share allergic or inflammatory mechanisms as seen with asthma. Squamous carcinoma, a type of skin cancer, is also unrelated to atopic dermatitis in terms of risk development as it is more associated with factors like sun exposure and other environmental carcinogens rather than atopic conditions.
