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. Read More

Notalgia paresthetica (NP) is a focal neuropathic itch condition manifesting in intense chronic or recurrent episodic itch in a hyperpigmented, macular, uni- or bilateral skin area located below and/or medially to the scapulae. Achieving satisfactory relieve in NP patients is challenging. In this case-series three female NP patients were treated with 8% capsaicin patches following a spatial quantification of their alloknetic area with a von Frey filament. Read More

Dysesthesia is a generic term for a cutaneous symptom--such as pruritus, burning, tingling, stinging, anesthesia, hypoesthesia, tickling, crawling, cold sensation, or even pain--without a primary cutaneous condition in a well-defined location that is often caused by nerve trauma, impingement, or irritation. There are multiple types of dysesthesias depending on the body location and the nerves involved. While location, exact symptoms, and etiologies might vary, the underlying theme is that these conditions are of neurologic origin and have dermatologic consequences. Read More

Notalgia paresthetica refers to an isolated mononeuropathy involving chronic localized itch or paresthesia most often at the skin of the scapula or surrounding regions. There are no specific skin manifestations except those arising from chronic scratching and rubbing. The specific etiology remains unknown; however, it has been theorized that the neuropathic itch is caused by sensory nerve entrapment involving the posterior rami of the T2 to T6 nerve root.

Chronic pruritus (CP) is a frequent symptom in the general population; in 8% of all patients, it has a neuropathic origin. CP is of neuropathic origin when nerve fiber damage is responsible for the symptom. The damage can be caused by compression or degeneration of the nerve fibers in the skin or extracutaneous in peripheral nerves or the central nervous system. Read More

Pain, burning, and paresthesias to a variable degree have also been reported.

It generally is a chronic noncurable condition with periodic remissions and exacerbations. While the dermatologic syndrome may be multifactorial in etiology, a possible association with underlying cervical spine disease should be evaluated for proper treatment. Read More

Notalgia paresthetica is a chronic sensory neuropathy characterized by pruritus of the upper to middle back, typically below the left shoulder blade. Symptoms may include pain, hyperesthesia, paresthesia, and hyperpigmentation of the affected area. Although the etiologic process of this condition is poorly understood, recent correlations with degenerative spinal changes suggest that spinal nerve impingement may play a role. Read More

Notalgia paresthetica is a rare nerve compression. From the Greek word noton, meaning "back," and algia, meaning "pain," "notalgia paresthetica" implies that symptoms of burning pain, itching, and/or numbness in the localized region between the spinous processes of T2 through T6 and the medial border of the scapula constitute a nerve compression syndrome. The compressed nerve is the dorsal branch of the spinal nerve. Read More

Currently, notalgia paresthetica (NP) is a poorly-understood condition diagnosed on the basis of pruritus, pain, or both, in the area medial to the scapula and lateral to the thoracic spine. It has been proposed that NP is caused by degenerative changes to the T2-T6 vertebrae, genetic disposition, or nerve entrapment of the posterior rami of spinal nerves arising at T2-T6. Despite considerable research, the etiology of NP remains unclear, and a multitude of different treatment modalities have correspondingly met with varying degrees of success. Read More

Botulinum toxin could represent nowadays a new treatment modality especially for cutaneous conditions in course of which conventional treatments remain unsuccessful. Besides palmar and plantar hyperhidrosis, botulinum toxin has demonstrated efficacy in different conditions associated with hyperhidrosis, such as dyshidrosis, multiple eccrine hidrocystomas, hidradenitis suppurativa, Frey syndrome, but also in different conditions worsened by hyperhidrosis such as Hailey-Hailey disease, Darier disease, inversed psoriasis, aquagenic palmoplantar keratoderma, pachyonychia congenital. Moreover, different cutaneous conditions associated with sensitive disorders and/or neurological involvements could benefit from botulinum toxin, for example anal fissures, leg ulcers, lichen simplex, notalgia paresthetica, vestibulitis.

Brachioradial pruritus is characterized by the presence of pruritus on the lateral aspect of the arms. The etiology of this enigmatic entity is the subject of some debate some authors claim that brachioradial pruritus is a photodermatosis whereas others attribute it to the presence of underlying cervical radiculopathy. In these case reports, we present our experience with brachioradial pruritus and discuss the role of underlying neuropathy in its etiology and that of other types of localized pruritus such as notalgia paresthetica, anogenital pruritus, and burning mouth syndrome.

Neuropathic and psychogenic itch are two entities that have not been well studied. Neuropathic itch is related to pathology located at any point along the afferent pathway of the nervous system. It could be related to damage to the peripheral nervous system, such as in postherpetic neuropathy, brachioradial pruritus, notalgia paresthetica, and in central nervous system damage as a result of spinal cord tumors and demyelinization diseases such as multiple sclerosis.

There is yet no established mode of curative treatment for notalgia paresthetica (NP). We had previously shown a correlation of NP localization with relevant spinal changes which led us to speculate on the possible role of spinal nerve impingement in the pathogenesis of this entity. Based on these findings we aimed to investigate the possible effect of physical therapy in selected cases of NP. Read More

We report the case of a patient who developed notalgia paresthetica during the recovery from a neuralgic amyotrophy. A 23-year-old woman had a typical neuralgic amyotrophy (severe shoulder pain, followed by a long thoracic nerve palsy); five months after the onset of pain, when scapular winging was improving, she began to feel a burning sensation in a restricted interscapular area, on the same side. Electromyography was consistent with a long thoracic nerve neuropathy, with minor neurogenic changes in deltoid and biceps brachii. Read More

Intractable localised segmental pruritus without a rash has been reported over the years under various titles depending on the area of the body affected. Notalgia paresthetica and brachioradial pruritus are the two terms used for what is believed to be a form of neuropathy. The clinical observations reported here suggest that other localised cases of pruritus exist that share common clinical features, and the term neurogenic pruritus is suggested to encompass these under one clinical condition.
