nevus

This term is primarily used in clinical and dermatological settings to describe a mole or birthmark. It carries a neutral, medical connotation, distinguishing it from the more casual term mole, which is used in everyday conversation. In a medical report, using this term signals a precise anatomical observation rather than a general description.

Because it is derived from Latin, the word follows specific pluralization patterns. While the standard English plural nevi is the most common form in medical literature, the anglicized plural nevuses is also acceptable, though less frequent in professional contexts.
