The nail is a complex cutaneous structure that consists mainly of the nail matrix, nail plate, nail bed, cuticle (eponychium), and nail folds. The cuticle is an outgrowth of the proximal fold, which is situated between the skin of the digit and the nail plate, providing a waterproof seal from external irritants and pathogens.

Paronychia is as an inflammatory reaction of one or more of the three nail folds, proximal or lateral ones, surrounding finger- or toe-nails. It is most commonly divided into acute and chronic.

Pus formation can proximally separate the nail from its underlying attachment, causing elevation of the nail plate. Recurrent acute paronychia may result into chronic paronychia.

The diagnosis of acute paronychia is based on a history of trauma and findings on physical examination of nail folds. The digital pressure test may cause blanching of the overlying skin and clear demarcation of the abscess, by applying light pressure to the distal volar aspect of the affected digit. In case of severe infection or abscess, cultures should be obtained to identify the responsible pathogen and to exclude methicillin- resistant S. aureus (MRSA) infection.13

Other causes of acute paronychia or other medical conditions that may involve the proximal nail fold and mimic acute paronychia include psoriasis, Reiter syndrome and herpetic whitlow.10 Herpetic whitlow typically appears as recurrent single or grouped blisters with a honeycomb appearance and occurs in health care professionals and healthy children, as a result of topical inoculation.12,8 Diagnosis can be confirmed by Tzanck testing or viral culture.
