A man has come in to the clinic because he is afraid he might have skin cancer. During the skin assessment, the nurse notices several areas of pigmentation that look greasy, dark, and "stuck on' on his skin. Which of the following is the best prediction?
Correct Answer: D
Rationale: The correct answer is D: He probably has seborrheic keratosis, which do not become cancerous. Seborrheic keratosis typically appear as greasy, dark, and "stuck on" pigmented growths on the skin, commonly seen in older adults. They are benign and do not progress to skin cancer. This conclusion is based on the characteristics of seborrheic keratosis and the fact that they are not associated with malignancy.
Choice A (senile lentigines) is incorrect because although they are also common in older adults, they are flat and dark spots rather than raised growths. Choice B (actinic keratoses) is incorrect as they are precancerous lesions related to sun exposure, leading to a risk of developing squamous cell carcinoma, not basal cell carcinoma. Choice C (acrochordons) are skin tags and not precursors to squamous cell carcinoma.
