Nodular melanoma is most commonly found in which locations?

1. Back and chest

2. Arms and legs

3. Extremities

4. Head and neck

The correct answer is: Extremities

Nodular melanoma is most commonly found on the extremities, which include both the arms and legs. This subtype of melanoma tends to present as a rapidly growing, pigmented nodule and is notable for its vertical growth phase right from the beginning, often making it more aggressive than other types. The involvement of the extremities can be attributed to a combination of factors including sun exposure and the particular skin characteristics of those areas. While other sites such as the back and chest, head and neck, or arms may also see occurrences of melanoma, the frequency and clinical presentation of nodular melanoma are more prominently associated with the extremities. Understanding this can aid in both diagnosis and awareness for early detection, as it highlights the importance of examining these regions for any suspicious lesions or changes.
