Patient's question:
Boy, 4 years old, has been sick for 3 weeks with improvement, lower body with multiple red spots that sometimes become patches. Often recurrentDoctor's answer:
A general term for the color change of the skin and mucous membranes after bruising and bleeding. Clinically, it manifests as petechiae, purpura, and ecchymosis, which are generally not elevated above the skin surface, except in allergic purpura when they may slightly protrude. Initially, they appear purplish-red, non-blanchable upon pressure, and gradually fade over time, turning yellow and disappearing after about two weeks. In such cases, it is important to rest, avoid excessive fatigue and overexertion, pay attention to warmth preservation to prevent cold exposure, and avoid cold air irritation. Additionally, focus on enhancing nutrition by consuming nutrient-rich and easily digestible foods, such as fresh vegetables, to replenish vitamins.
