Hyperpigmented Papules on the Tongue of a Child

Abstract

A 9-year-old Black boy presented to the dermatology clinic for evaluation of dark spots on the tongue. The family first noted these spots 5 months prior and reported that they remained stable during that time. The patient's medical history was notable for autism spectrum disorder and multiple food allergies. His family history was negative for similar oral pigmentation or other pigmentary anomalies. A review of systems was positive only for selective eating and rare nosebleeds. Physical examination revealed numerous dark brown, pinpoint papules across the dorsal aspect of the tongue. No hyperpigmentation of the buccal mucosae, lips, palms, or soles was identified. Several light brown streaks were present on the fingernails and toenails, consistent with longitudinal melanonychia. A prior complete blood cell count was within reference range. WHAT'S YOUR DIAGNOSIS?a. Addison disease b. black hairy tongue (or lingua villosa nigra) c. hereditary hemorrhagic telangiectasia d. Peutz-Jeghers syndrome e. pigmented fungiform papillae of the tongue Eligible for 1 MOC SA Credit From the ABD This Photo Challenge in our print edition is eligible for 1 self-assessment credit for Maintenance of Certification from the American Board of Dermatology (ABD).
