Scabies incognito presenting as urticaria pigmentosa in an infant.
Misdiagnosis is frequent in scabies of infants and children because of a low index of suspicion, secondary eczematous changes, and inappropriate therapy. Topical or systemic corticosteroids may modify the clinical presentation of scabies and that situation is referred to as scabies incognito. We describe a 10-month-old infant with scabies incognito mimicking urticaria pigmentosa.
