What symptom is commonly associated with malignant melanoma?

The correct choice highlights that a change in a nevus is a common symptom associated with malignant melanoma. This typically involves alterations in the size, shape, color, or texture of an existing mole or skin lesion. Such changes can include asymmetry, irregular borders, multiple colors, or an increase in diameter, often described using the ABCDE criteria (Asymmetry, Border irregularity, Color variation, Diameter greater than 6mm, Evolution over time).

These changes can serve as warning signs and are critical for early detection of melanoma, which can significantly impact prognosis and treatment outcomes. Recognizing any modifications in a nevus is essential for individuals and healthcare providers to monitor skin health. The other options may describe different skin conditions or lesions that are not specific indicators of malignant melanoma.
