A case of ingrown toenail accompanied by extreme soft tissue hypertrophy to the extent of invisible nail.

Ingrown nails occur when the nail fold grows inwards into the nail bed. This condition affects daily life and causes a loss of labor, and therefore, should be meticulously tackled and immediately treated. Ingrown nail is categorized in three stages based on pain, erythema, infection, drainage, and the presence of granulation tissue. We present hypertrophic tissue excision and bilateral partial matrix excision in an unclassified case of ingrown toenail in which the bilateral side wall hypertrophy covered the entire nail; normal tissue of the nail was invisible, along with first year follow-up results.
