1. Onychomycosis

2. Onychogryposis

3. Onychocryptosis

4. Xerosis

The correct answer is: Onychocryptosis

The condition where a segment of the nail plate penetrates into the nail groove and subcutaneous tissue is known as onychocryptosis, commonly referred to as an ingrown nail. This occurs when the edge of the nail grows into the surrounding soft tissue, leading to pain, inflammation, and sometimes infection. It often affects the toenails, particularly the big toe, and can be influenced by factors such as improper nail trimming, tight footwear, or genetic predisposition. Understanding this condition is essential for effective diagnosis and management. Treatments may include proper nail care, wearing appropriate footwear, and in some cases, surgical intervention to remove part of the nail if conservative measures do not resolve the issue. Recognizing the signs and symptoms of onychocryptosis is vital in preventing potential complications associated with this condition.
