ABSTRACT

Cutaneous mosaicism may be encountered with different patterns. Type II mosaicism - checkerboard pattern is characterized by flag-like areas with a sharp midline separation. The speckled lentiginous nevus (BLN) and Becker nevus are clinical examples of this pattern. A 38-year-old woman attended the outpatient clinic with a complaint of spots located over the left upper part of her body.

These spots had been present from about eight years of age and showed a progressive course. Her mother also had a history of similar lesions. On dermatologic examination a diffuse, flag-like patch including brown macules was present over the left upper anterior trunk and left upper extremity. In this case report a case having BLN localized in type II mozaisizm- checkerboard pattern, which has not been reported previously in the Turkish literature, was presented.
