Port-wine stains are also known as which of the following?

Port-wine stains are indeed referred to as nevus flammeus. This term specifically describes flat, pink or purple birthmarks that are caused by a dilution of small blood vessels under the skin. These marks can vary in size and tend to darken with age, often remaining throughout an individual's life. Understanding this terminology is important in neonatal care, as port-wine stains can sometimes be associated with other medical conditions, and recognizing them accurately can guide appropriate monitoring and intervention.

The other terms listed refer to different types of skin lesions. Nevi simplex are flat, light pink birthmarks commonly referred to as "angel's kiss" or "stork bite," typically found on the nape of the neck or between the eyes. Strawberry hemangiomas are raised, red lesions that are a result of a proliferation of blood vessels and usually develop shortly after birth. Café-au-lait macules are flat, pigmented birthmarks with a light-brown color that can appear anywhere on the body and are often associated with genetic conditions, but they are not linked to the vascular nature of port-wine stains.

By understanding these distinctions, practitioners can more accurately diagnose and educate families about different types of skin markings that may appear in neonates.
