Case 2: Atopic dermatitis
The legs of this patient with atopy, A, were irritated by his shin guards, which resulted in an itchy sensation and subsequent scratching. Because the rash had not responded to topical corticosteroids, the boy was given ultra thin hydrocolloid dressing (Duoderm Extra Thin) to wear when he played soccer.
Staphylococcal infections are typically painful. Unlike the eruption in this patient, folliculitis features multiple erythematous papules and pustules. Contact dermatitis can be patchy, although the pattern seen in this patient would not be typical. The presence of multiple lesions would be unusual for a dermatophyte infection.
