Which features are characteristic of a typical melanoma lesion?

A typical melanoma lesion is characterized by certain distinguishing features that help in its identification. The correct choice describes these characteristics accurately. Melanoma lesions often present with an asymmetrical shape, irregular borders, and can have multiple colors, including dark brown as well as red and blue areas. These colors and the flat, irregular shape suggest potential malignancy, as melanoma may encompass a variety of colors and a non-uniform appearance.

In contrast, other descriptions do not align with typical melanoma features. For example, lesions that are symmetrical and light brown tend to represent benign nevi or moles rather than melanoma. Similarly, the presence of a uniform color and smooth texture is more consistent with normal moles or benign skin lesions, as melanoma typically showcases irregularities. A bright red, raised, and shiny lesion may suggest a different dermatological condition, such as a dermatofibroma or a hemangioma, rather than melanoma.

Understanding these specific characteristics is crucial for early detection and intervention in cases of melanoma, which is a critical aspect of oncology nursing assessments.
