What condition describes an ingrown nail where a segment of the nail plate penetrates into the nail groove?

1. Onychomycosis

2. Onychatrophia

3. Onychocryptosis

4. Onychogryposis

The correct answer is: Onychocryptosis

The condition characterized by a segment of the nail plate penetrating into the nail groove is known as onychocryptosis, commonly referred to as an ingrown toenail. This occurs when the edge of the nail grows into the skin surrounding the nail, causing pain, inflammation, and sometimes infection. Onychocryptosis can be the result of various factors such as improper nail trimming, wearing tight shoes, or genetic predisposition. Recognizing this condition is crucial for proper management, as it may require interventions ranging from conservative measures, like proper nail cutting techniques and foot hygiene, to more invasive treatments such as nail removal in severe cases. In contrast, onychomycosis refers to a fungal infection of the nails, which presents differently and does not involve the nail penetrating the surrounding tissue. Onychatrophia describes the wasting away or atrophy of the nail plate, which does not involve the ingrowth aspect of the nail. Onychogryposis is characterized by an abnormal curvature and thickening of the nail, rather than an ingrown condition. Each of these conditions has distinct characteristics that differentiate them from onychocryptosis.
