Three Cases of Retronychia / 대한피부과학회지

Retroncyhia shows ingrowth of the nail toward the proximal nail folds. Initial events start from minor trauma of the digital pulp that disturbs longitudinal nail growth. This disturbed growth of the nail changes the growth direction to the proximal nail folds, leading to persistent paronychia, formation of granulation tissue, and other nail changes. Simple avulsion is curative and can improve most symptoms. There are few reports about retronychia in the English literature, and we report 3 cases of retronychia here.

A Case of Infantile Ingrowing Nail Associated with Candidal Onychomycosis / 대한의진균학회지

Ingrowing nail is that the soft tissue of the side of the nail is penetrated by the edge of the nail plate, resulting in pain, inflammation, the formation of granulation tissue. This disease is common in adolescence and adult, but rare in infant. So far, there has not been reported ingrowing nail associated with onychomycosis mycologically confirmed. We report a case of congenital hypertrophic lip of hallux, a subtype of infantile ingrowing nail, in a 6 month-old-male, associated with onychomycosis due to Candida parapsilosis.
