Description: Dermoscopic description: Atypical network, multicomponent pattern with a blue-gray coloration Atypical pigment network
History:
The patient has a history of an excised pigmented lesion done with laser a year ago. Some time after this she has developed a new lesion precisely at the excision site. No previous histopathology report (laser excision). I have seen very often recurrent nevus after laser excision. Laser excision is not recommended for melanocytic lesions.
As Ian McColl said:Always check the original histopathology of a previous excision. In benign recurrences the pigment usually does not extend beyond the scar margins. See this reference
