Which condition involves abnormal stretching around the nail plate?

The condition that involves abnormal stretching around the nail plate is mail pterygium. This condition is characterized by the abnormal adherence of the skin to the nail plate, often leading to the formation of a bridge of tissue that can restrict the movement of the nail and alter its growth. It can occur as a result of various underlying issues, such as injury, nail infections, or skin disorders, and may result in a noticeable change in the appearance of the nail and surrounding tissue.

Understanding this condition is important for nail technicians, as they must identify and differentiate it from other nail and skin conditions in order to provide appropriate care and treatment options for their clients. The other conditions listed involve different processes or changes that do not specifically relate to the abnormal stretching around the nail plate, which is the hallmark of mail pterygium.
