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.
虽然后颈部和皮肤褶皱处的黑棘皮病很常见，但鼻翼上皱襞处的黑棘皮病却很罕见。我们报告一例16岁肥胖非裔美国男孩的病例，其鼻翼上皱襞处有色素沉着斑。临床医生应注意这种罕见表现，因为新诊断的黑棘皮病应促使对胰岛素抵抗进行检查。
