Introduction
The recurrent nevus arises as a result of melanocyte proliferation at the site of non-radical removal of a pre-existing, benign nevus. It is clinically characterized by, inter alia, uneven pigmentation and asymmetry, so some cases may resemble melanoma and pose diagnostic difficulties.

Case reports
The article presents patients with recurrence of melanocytic lesions previously removed by a non-radical laser method. The attention was paid to the wide clinical spectrum, dermoscopic presentation and the principles of differentiating recurrent nevi from melanoma.

Conclusions
Most of the recurrent melanocytic proliferations in the scar are a result of the previous non-radical removal of benign nevus. The primary differential diagnosis includes mainly melanoma. Extending of the pigment beyond the scar area, age over 30, head/neck location, and chaos observed on dermoscopy are factors that increase the likelihood of malignant lesion diagnosis.
