Which statement regarding giant congenital nevus is true?

• A. It has the lowest risk among congenital nevi
• B. It is not associated with cancer risk
• C. It carries higher malignant transformation risk than other nevi
• D. It is always easily treated

Answer: (C)

Giant congenital nevus is present at birth and involves a very large surface area with a higher burden of melanocytes, often with satellite lesions. That greater number of melanocytes and the size of the lesion markedly increase the risk that some cells may undergo malignant transformation over time, compared with smaller congenital nevi or acquired nevi. Because this risk persists across the patient’s lifetime and tends to rise with size and complexity of the lesion, it is true that this condition carries a higher malignant transformation risk than other nevi. This is not a situation with no cancer risk, nor is it typically easy to treat; large lesions can require complex, staged surgeries or skin reconstruction, and complete removal isn’t always feasible. Regular surveillance and patient education about warning signs are essential, given the ongoing risk.
