Acute and Chronic Paronychia Revisited: A Narrative Review.

Paronychia refers to the inflammation of the tissue which immediately surrounds the nail and it can be acute (<6 weeks duration) or chronic (>6 weeks duration). Disruption of the protective barrier between the nail plate and the adjacent nail fold preceded by infectious or noninfectious etiologies results in the development of paronychia. A combination of general protective measures, and medical and/or surgical interventions are required for management. This review explores the pathogenesis, clinical features, differential diagnosis, medical, and surgical management of paronychia. For the purpose of this review, we searched the PubMed, Cochrane, and Scopus databases using the following keywords, titles, and medical subject headings (MeSH): acute paronychia, chronic paronychia, and paronychial surgeries. Relevant review articles, original articles, and case reports/series published till February 2020 were included in this study.
