Condition characterized by bleeding under the nail plate due to trauma is called?

Splinter hemorrhages are indeed characterized by the presence of small, linear streaks or spots of bleeding that occur beneath the nail plate. This condition typically results from trauma to the nail matrix or bed, which can disrupt the blood vessels in this area, allowing blood to leak and become trapped underneath the nail. The appearance of these hemorrhages resembles splinters, hence the name.

In contrast, pyogenic granuloma refers to a type of skin growth that is often red, raised, and can bleed easily, but it does not specifically imply bleeding under the nail plate as a direct response to trauma. Hangnail is a condition involving a small piece of skin that is torn at the side of a fingernail, which does not cause bleeding beneath the nail itself. Onychophagy is the technical term for nail biting, a habit that affects the nails but again does not involve bleeding under the nail plate due to trauma. Thus, splinter hemorrhages uniquely describe bleeding underneath the nail, making this option the correct answer.
