The metabolic salute: A unique presentation of transverse nasal acanthosis nigricans and allergic rhinitis in an obese pediatric patient

다국어 초록 (Multilingual Abstract)

Acanthosis nigricans (AN) is a well‐known cutaneous condition that is most commonly associated with insulin resistance and obesity when present in a pediatric patient. We present a unique presentation of AN in an adolescent African American girl with a history of perennial allergic rhinitis. She presented with AN affecting the neck, axillae, as well as the transverse nasal crease, a consequence of habitual pushing of the nasal tip upward due to chronic obstruction and itching from allergic rhinitis known as the “allergic salute.” All providers should be aware of this rare presentation, as the presence of AN should prompt additional evaluation to determine the underlying cause and effect of appropriate treatment.
