Abstract
ABSTRACT: Notalgia paresthetica is a dermatologic condition with prominent primarily left unilateral pruritis and raised erythematous rash with hyperpigmentation at the medial or inferior scapula. The etiology is unknown. A comprehensive review of the literature was performed with a structured analysis of previous theories. There is no consistent imaging or functional test to support any of the previously proposed mechanisms. A new theory is presented with a unifying theme of all previous treatments and is supported with results of the first electrical impedance myography testing in this condition.
