The recurrence of melanocytic nevi following removal is a recognized phenomenon in dermatology. It refers to the reappearance of a mole, either at the same location or in close proximity to where it was previously excised. This can manifest as a renewed pigmentation or a fully formed nevus.
Understanding the causes of this regrowth is clinically important for managing patient expectations and ensuring appropriate treatment strategies. Knowledge about the likelihood of recurrence helps guide decision-making regarding removal techniques and the need for follow-up monitoring. Historically, incomplete excisions were often attributed as the primary cause. However, contemporary research indicates that other factors also play a significant role.
