What type of dermatitis cannot be cured but can be well controlled?

A. Seborrheic dermatitis, especially in infants (cradle cap), is usually self-limiting and often resolves on its own with appropriate skin care and medicated shampoos. It can generally be cured or cleared rather than managed long-term. B. Atopic dermatitis (eczema) is a chronic, relapsing inflammatory skin condition. It cannot be cured, but symptoms can be well controlled with strategies such as moisturizers, topical corticosteroids, antihistamines, avoiding triggers, and gentle skin care. Management focuses on preventing flare-ups and reducing itching and inflammation. C. Diaper dermatitis is usually acute and treatable. With frequent diaper changes, barrier creams, and proper hygiene, it can be resolved quickly and does not require long-term management in most cases. D. Contact dermatitis is caused by exposure to an irritant or allergen. It can often be cured or cleared by avoiding the trigger and using topical treatments, such as corticosteroids, rather than requiring lifelong management.
