Abstract Although acanthosis nigricans of the posterior neck and intertriginous areas is common, acanthosis nigricans of the supra‐alar creases is rare. We present the case of an obese 16‐year‐old African American boy with hyperpigmented plaques along the supra‐alar creases of his nose. Clinicians should be aware of this rare manifestation, because newly diagnosed acanthosis nigricans should prompt examination for insulin resistance.
