What is another name for a port wine stain?

1. Salmon patch

2. Nevus simplex

3. Nevus flammeus

4. Cutis marmorata

The correct answer is: Nevus flammeus

A port wine stain is specifically referred to as a nevus flammeus. This term describes a type of vascular birthmark that appears as a flat, reddish-purple mark on the skin, typically present at birth or shortly thereafter. The name 'nevus flammeus' highlights its vascular nature—'nevus' refers to a birthmark or skin lesion, and 'flammeus' relates to its flame-like color and appearance, which mimics that of red wine. Understanding this nomenclature is important for healthcare professionals as it helps in identifying and communicating about various skin conditions. Other terms provided in the choices denote different types of skin markings or birthmarks. For instance, a salmon patch refers to a pinkish stain often found on the nape of the neck or eyelids, while a nevus simplex generally denotes a light pink birthmark common in babies, also known as an angel's kiss or stork bite. Cutis marmorata refers to a transient mottled or marbled appearance of the skin, often due to cold exposure and not specifically related to vascular lesions like a port wine stain. Knowing the distinct terminology for these conditions enhances comprehension and ensures accurate diagnosis and communication in clinical practice.
