Which type of nevus does not grow or fade away over time?

• A. Telangiectatic nevi
• B. Strawberry mark
• C. Port wine stain
• D. Capillary malformation

Answer: (C)

The port wine stain is a type of nevus that remains consistent over time without showing signs of growth or fading. These lesions are usually flat and have a pink to dark red color, caused by a localised excess of capillaries. Unlike other types of nevi that may change characteristic features or may even disappear as a child grows, port wine stains are permanent and do not regress. In contrast, telangiectatic nevi, also known as angel's kisses or stork bites, are common in newborns and typically fade within the first year of life. Strawberry marks, or infantile hemangiomas, are another type that often grows rapidly but later shrinks and fades significantly during childhood. Capillary malformations can include a variety of vascular birthmarks but may also not behave the same way as port wine stains, which are specifically defined by their permanence.
