Notalgia Paresthetica and Multiple Endocrine Neoplasia Syndrome 2A: A Case Report.

Notalgia paresthetica is characterized by a hyperpigmented macular pruritic skin lesion most commonly localized unilaterally in the middle and upper back region. This condition has been reported in association with multiple endocrine neoplasia syndrome type 2A (MEN 2A) in several families; it rarely affects children and it may serve as an early marker of MEN 2A. We report a 9-year-old girl diagnosed with MEN 2A and notalgia paresthetica.
