What is the term for a blood clot that forms under the nail plate, presenting as a dark purplish spot?

The term for a blood clot that forms under the nail plate and presents as a dark purplish spot is known as a bruised nail. When trauma occurs to the nail bed, such as hitting or crushing the nail, it can cause bleeding beneath the nail, leading to the characteristic discoloration. This condition is commonly seen in situations where there is localized pressure or injury.

The appearance of a bruised nail can be alarming, but it often heals over time as the nail grows out. Understanding this is important for nail care practitioners as they assess nail health and advise clients on proper treatment and care. Knowledge of the symptoms and causes can help in distinguishing it from other nail conditions, which is essential for providing effective client care.
