In simple words: Atopic dermatitis, or eczema, is a common skin condition that causes itchy, red, and sometimes bumpy skin.It often affects the creases of the elbows and knees, but can appear anywhere.It comes and goes and can be treated with creams and other therapies to help manage the symptoms.

Atopic dermatitis (L20) is a chronic inflammatory skin condition characterized by intensely itchy, inflamed skin.It often presents with erythema (redness), papules (raised bumps), vesicles (small blisters), and excoriations (scratch marks). The distribution of the rash can vary, but it commonly affects flexural areas (like the inside of the elbows and knees) in older children and adults, while infants often experience widespread involvement.The condition is associated with a genetic predisposition and often involves a disruption of the skin barrier, leading to increased sensitivity and dryness.The severity can fluctuate, with periods of exacerbation and remission.Atopic dermatitis can be further specified with additional codes to indicate the location and severity of the rash.

Example 1: A 6-month-old infant presents with widespread erythematous rash with weeping lesions, consistent with infantile eczema (atopic dermatitis).The physician diagnoses atopic dermatitis and prescribes a mild topical corticosteroid cream and emollients., A 10-year-old child with a history of atopic dermatitis experiences a flare-up affecting the flexural areas. The physician assesses the severity, discusses environmental triggers, and adjusts the treatment plan to include a stronger topical corticosteroid and allergy testing., A 30-year-old adult presents with chronic, intensely itchy plaques on the hands and feet, consistent with atopic dermatitis. The physician orders allergy testing, recommends emollients, and suggests behavioral therapy for managing the chronic itch.

Detailed history of the rash, including onset, duration, distribution, associated symptoms (itching, burning), and potential triggers (allergens, irritants, stress).Physical examination documenting the morphology and distribution of the rash.Results of any allergy testing or other relevant investigations (e.g., skin prick testing).Treatment plan, including specific medications prescribed, and response to treatment.

** Atopic dermatitis is a chronic condition that requires ongoing management.The treatment plan should be individualized based on the patient's age, severity of the condition, and response to treatment.
