Atopic Dermatitis models / Pathology background / Clinical views

Atopic Dermatitis or atopic eczema is a chronic inflammatory skin disease characterized by itchy skin lesions and rashes. Though the condition affects people of all ages, it is primarily common among infants and children. Symptomatic treatment of atopic dermatitis relies primarily on the use of topical formulations (corticosteroids and immunosuppressors). Physicians consider current oral treatments to have limited value in the treatment of atopic dermatitis; antihistamines are the primary class of oral agents used. Due to its chronic and relapsing nature, atopic dermatitis presents a global public health concern, with reported lifetime prevalence ranging between 10%-20% in children and 1%-3% in adults
