A giant congenital nevus (GCN), which is also known as a congenital pigmented nevus, is often discovered at birth or in the child’s first year of life. It is often characterized as a dark, hairy blotch or patch on the skin that is larger than 6 cm. These little patches could seem harmless, but it is important for parents to keep an eye on this skin condition as it can lead to other more dangerous conditions such as skin cancers. In such cases, early detection and treatment is crucial.
What causes GCN?
There are different factors believed to be the major culprits behind GCN. Experts say that these marks can be caused by problems inside the womb during pregnancy. In some cases, bathing trunk nevi is inherited. Most commonly, however, it can occur with the growth and development of fatty tissue cells, a condition known as lipoma. It can also be due to other conditions such as neurofibromatosis, spina bifida, and other nevi. When such nevi appear smaller in children, they usually do not cause any problems as they grow. On the other hand, although rare, the giant congenital nevi or the much larger nevi can reveal hidden dangers.
Look out for the signs and symptoms!
Symptoms of GCN are easy to spot. This dark nevus may appear brown, hairy, smooth, wart-like, or irregular, with either regular or uneven borders. These are commonly found on the back or the abdomen of the patient, but can also be found less often on the mouth, arms, legs, the palms, and soles.
