title: [Symmetrically enlarging pigmented lesion in an adolescent].
abstract: A 16-year-old boy with multiple nevi presented with an enlarging pigmented lesion on his right chest. Previously excised nevi were all benign. Dermoscopy of the symmetrical lesion revealed a trizonal globular-homogeneous pattern. A peripheral rim of brown globules was followed by a zone with homogeneous pigmentation. The centre of the lesion showed black dots and globules. Histopathology confirmed a dysplastic compound nevus and found no diagnostic aspects of pigmented spindle cell nevus (Reed).
