What is the name for a crack in the skin that may penetrate into the dermis?
Keloid
Fissure
Excoriation
Crust
The correct answer is: Fissure
A crack in the skin that may penetrate into the dermis is referred to as a fissure. This term specifically describes a linear break or split in the skin that can be painful and may lead to deeper tissue involvement. Fissures are often seen in conditions such as dry skin, eczema, or fungal infections, where the skin loses its elasticity and moisture, making it more prone to cracking. In contrast, a keloid is an overgrowth of scar tissue that can develop after an injury, excoriation refers to a scratch or abrasion on the skin's surface, and crust is a collection of dried serum, blood, or other biological material on the skin's surface. Understanding the specific definitions and characteristics of these different terms is essential for effective skin assessment and treatment in esthetics.
