Notalgia paresthetica (NP) is a rarely reported T2-T6 sensory neuropathy whose etiology and treatment are not fully established. Although it is believed to be common in dermatological practice, it remains under-recognized, under-diagnosed, and therefore under-reported. This case-report provides a physical medicine and rehabilitation (PMR) perspective on NP diagnosis and treatment. Read More

Notalgia paresthetica (NP) is an underdiagnosed condition that presents with unilateral pruritus medial to the scapula on the midback with or without an associated hyperpigmented or hypopigmented macule. There is a paucity of recent reviews on this chronic cutaneous neuropathy in peer-reviewed journals. Current theories propose the condition is likely multifactorial, including spinal entrapment and muscular compressive neuropathy. Read More

Notalgia paresthetica, a neurosensory syndrome that typically occurs on the upper back, has multiple clinical symptoms with variable degrees of expression in each individual afflicted with the condition. The involved site is usually hyperpigmented and is associated with burning, coldness, hypoesthesia, increased pain, pruritus and/or tingling. In the affected area, the number of nerve fibers may be increased and the cutaneous sensory nerves are altered secondary to localized impingement, central injury, or both. Read More

Notalgia paresthetica is a syndrome of unilateral, chronic pruritis that is associated with burning pain, paresthesia, numbness, and hyperesthesia localized to the medial and inferior scapula. The condition does not respond to anti-inflammatory drugs or traditional antipruritic agents and has variable responses to numerous other reported pharmacologic and nonpharmacologic therapies. Although the etiology is thought to be nerve impingement, neurologic and musculoskeletal causes are often not considered in the differential diagnosis. Read More

Objective: The purpose of this paper is to elucidate this little known cause of upper back pain through a narrative review of the literature and to discuss the possible role of the dorsal scapular nerve (DSN) in the etiopathology of other similar diagnoses in this area including cervicogenic dorsalgia (CD), notalgia paresthetica (NP), SICK scapula and a posterolateral arm pain pattern.

Background: Dorsal scapular nerve (DSN) neuropathy has been a rarely thought of differential diagnosis for mid scapular, upper to mid back and costovertebral pain. These are common conditions presenting to chiropractic, physiotherapy, massage therapy and medical offices. Read More

Laser treatment is a relatively new and increasingly popular modality for the treatment of many dermatologic conditions. A number of conditions that predominantly occur in women and that have a paucity of effective treatments include rosacea, connective tissue disease, melasma, nevus of Ota, lichen sclerosus (LS), notalgia paresthetica and macular amyloidosis, and syringomas. Laser therapy is an important option for the treatment of patients with these conditions. Read More

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

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.

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

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.
