A 35-year-old man enjoys sailing and is at increased risk for melanoma, particularly in which location?

• A. Back
• B. Chest
• C. Palms
• D. Scalp

Answer: (C)

The correct answer is associated with an increased risk for melanoma in the palms of the hands. This location is particularly relevant for individuals who engage in outdoor activities, such as sailing, which can lead to prolonged sun exposure. While melanoma is commonly seen on sun-exposed areas of the skin, it can also develop in areas that might not receive direct sunlight, including the palms and soles.

The skin on the palms is thicker than on other areas, which may provide some protection against superficial damage from UV radiation. However, this thickened skin can still be impacted by UV exposure, particularly in individuals who might neglect to apply sunscreen to these less visible areas of their body.

Additionally, melanoma on the palms is often a sign of acral lentiginous melanoma, which is a subtype of melanoma that occurs mainly on non-sun-exposed areas, including the palms and soles, and is more prevalent among individuals with darker skin. Understanding this risk factor is crucial for early identification and prevention, especially in active individuals like sailors who may experience intensified sun exposure.

Other options, while also potential sites for melanoma development, are comparatively more common for lesions due to direct sun exposure rather than the specific risks associated with prolonged UV exposure in typical outdoor conditions.
