Ingrown toenail, or onychocryptosis, is a common inflammatory disease of the hallux. It results from the alteration of fit of the nail plate in the lateral nail fold. Ingrown toenails are usually seen in adolescents and young adults and can affect daily activities and social life. Generally, ingrown toenails are classified into three stages, including the inflammatory stage, the abscess stage, and the granulation stage. In this article, we present the rare case of a man with a diagnosis of paronychia with sporangium formation causing an ingrown toenail.
