Acral nevus
An acral nevus is a type of melanocytic nevus that occurs on the acral areas of the body, which include the palms, soles, and nail beds. These nevi are generally benign and are characterized by their distinct location on the body.
Characteristics[edit]
Acral nevi are typically small, pigmented lesions that can vary in color from light brown to black. They are usually round or oval in shape and have well-defined borders. The texture of an acral nevus can be smooth or slightly raised.
Histology[edit]
Under the microscope, acral nevi show nests of melanocytes at the dermoepidermal junction. These melanocytes are often arranged in a pattern that is distinct from nevi found on other parts of the body. The histological features help differentiate acral nevi from other pigmented lesions, such as acral lentiginous melanoma.
Differential Diagnosis[edit]
The primary concern with acral nevi is distinguishing them from melanoma, particularly acral lentiginous melanoma, which can also occur in the same locations. Dermatologists often use dermoscopy to examine the patterns and structures within the nevus to aid in diagnosis.
Management[edit]
Most acral nevi do not require treatment unless there are changes in size, shape, or color, which could indicate malignant transformation. Regular monitoring and biopsy may be recommended if there are any suspicious changes.
