Notalgia paresthetica: treatment review and algorithmic approach.

Area of Science:

• Neurology
• Dermatology

Background:

• Notalgia paresthetica (NP) is a sensory neuropathy affecting the back, presenting as a distinct hyperpigmented patch.
• Symptoms include localized itching and pain, with a relapsing-remitting course.
• NP is often underrecognized and difficult to treat, with conventional therapies showing variable results.

Purpose of the Study:

• To review existing treatments for notalgia paresthetica (NP).
• To evaluate the evidence level for the efficacy of various NP treatments.
• To propose a treatment algorithm for NP management.

Main Methods:

• A MEDLINE search was conducted using terms 'notalgia,' 'paresthetica,' and 'treatment.'
• All retrieved articles were included in this literature review.

Main Results:

• Treatment options encompass topical agents (e.g., capsaicin, anesthetic cream), systemic agents (e.g., gabapentin, amitriptyline), procedural modalities (e.g., botulinum toxin A, narrowband UVB), and physical therapy.
• No single treatment demonstrates superior efficacy.
• A tiered treatment approach is suggested.

Conclusions:

• Initiate NP treatment with topical agents or physical therapy.
• Progress to systemic agents if initial treatments are insufficient.
• Consider procedural modalities as a later option.
• Combining treatments with physical therapy may enhance sustained response.
