Abstract
Recurrent melanocytic lesions arise in a scar by a growth of lesion, that was not removed completely surgically or by cryodestruction, electrocautery or laser. The main task is to distinguish between recurrent melanocytic nevus and the recurrence of melanoma.
The initial histological report, if available, is very helpful. Clinical as well as dermatoscopic images of all recurrent lesions are bizarre.
Clinical and dermatoscopic presence of pigmentation beyond the border of the scar is the strongest indication for melanoma. Melanomas usually grow more eccentrically and the pigmentation pattern is chaotic.
If there is any suspition of melanoma, surgical excision and histopathologic examination are indicated. Because of the increasing number of recurrent melanocytic lesions arising after aesthetic procedures without histologic examination, this issue is a current topic.
