Which type of skin cancer is typically associated with pigmented skin lesions?

1. Melanoma

2. Ecchymosis

3. Tinea

4. Hypodermic

The correct answer is: Melanoma

Melanoma is a type of skin cancer that originates in the melanocytes, the skin cells responsible for producing melanin, which gives skin its color. This direct association between melanoma and pigmented skin lesions makes it a distinguishing factor for this type of cancer. The lesions can appear as moles or new growths on the skin, often varying in color from brown to black due to the higher concentration of melanin. Understanding this connection is crucial in clinical practice, as recognizing atypical pigmented lesions can lead to early diagnosis and treatment of melanoma, improving patient outcomes. In contrast, the other terms mentioned, such as ecchymosis, tinea, and hypodermic, do not relate to skin cancer and are associated with different medical conditions. Ecchymosis refers to bruising or discoloration of the skin due to bleeding beneath it, tinea is a fungal infection affecting the skin, nails, or hair, and hypodermic pertains to the subcutaneous tissue or injections made into that area. These distinctions further highlight why melanoma is the appropriate answer in this context.
