Spitz nevus

A 14-year-old boy presented a dark pigmented lesion on his lumbar area. Dermoscopy revealed a homogeneous pattern with a bluish pigmentation. Rare brown globules were found at the periphery. The lesion was excised and pathology revealed a dermal Spitz nevus.

Six dermoscopic patterns of Spitz nevus have been described:
-vascular pattern with dotted vessels
-globular pattern
-reticular pattern
-starburst pattern
-homogeneous pattern
-atypical pattern
