How is a Strawberry naevus best described?

A strawberry naevus, also known as a hemangioma, is characterized by its pink or red color and irregular shape. These lesions are typically flat at first but can become raised over time. Notably, they are known for their tendency to fade as the child grows, often significantly reducing in size or resolving completely by the age of one to two years. This natural regression is a critical feature distinguishing strawberry naevi from other types of skin lesions that may not have a similar life cycle.

In comparison, other options describe characteristics that do not align with the defining aspects of a strawberry naevus. For example, the assertion that they are usually present at birth and grow without fading does not apply, as many strawberry naevi develop shortly after birth and are notable for their regression. Additionally, the description of raised irregular marks that are permanent does not accurately reflect the transient nature of strawberry naevi, which typically do not remain for life. Lastly, the depiction of localized collections of melanocytes suggests a different type of skin lesion, such as a mole or pigmented lesion, which further distinguishes these from the vascular nature of a strawberry naevus.
