What is the medical term for a mole?

1. Neoplasm

2. Melanoma

3. Nevi

4. Dermatofibroma

The correct answer is: Nevi

The medical term for a mole is "nevi." This term refers to benign skin growths that are typically pigmented and can vary in size and color. Nevi are composed of clusters of melanocytes, the cells responsible for producing melanin, which gives skin its color. While moles are generally harmless, it's important to monitor any changes in size, color, or texture, as these can sometimes indicate underlying issues, but the term "nevi" specifically categorizes them as non-cancerous formations. In contrast, "neoplasm" broadly refers to any new and abnormal growth of tissue, which can include benign and malignant tumors, making it too general to specifically describe a mole. "Melanoma" is a type of skin cancer that arises from melanocytes, and while moles can potentially develop into melanomas, the term itself does not refer to a mole. "Dermatofibroma" is a distinct type of benign skin tumor that typically appears as a firm bump on the skin and is different from a mole. Therefore, "nevi" is the accurate term to represent moles in a medical context.
