There is no established system for the classification of atopic dermatitis. It may be classified into intrinsic atopic dermatitis and extrinsic atopic dermatitis according to means of allergic [[sensitization]]. Intrinsic atopic dermatitis is associated with normal serum [[IgE]] levels vs elevated total serum [[IgE]] levels.

Overview

There is no established system for the classification of atopic dermatitis. It may be classified into intrinsic atopic dermatitis and extrinsic atopic dermatitis according to the means of allergic sensitization. Intrinsic atopic dermatitis is associated with normal serum IgE levels vs elevated total serum IgE levels.

Classification

There is no established system for the classification of atopic dermatitis.

Atopic dermatitis may be classified according to the means of allergic sensitization into:[1][2]

Intrinsic atopic dermatitis Extrinsic atopic dermatitis
  • Elevated total serum IgE levels[7]
