Abstract

Spitzoid lesions represent a special group of melanocytic lesions that are usually difficult to diagnose. The terminology has been going through changes for decades and is still not quite completed.

Reed and Spitz nevi are considered to be benign and are typical for children and adolescents. Some of the malignant melanomas have "spitzoid features" and mimic both of these nevi groups.

Spitzoid lesions that cannot be reliably histologically categorized are usually diagnosed as atypical Spitz tumors. Dermoscopy plays an important role in the diagnostics.

Demoscopic images of Reed and Spitz nevi are well documented. Dermoscopic examination helps in the diagnostics of melanomas with spitzoid features and on the contrary, it enables follow-up without the need of excision in children with Reed nevus.

Surgical excisions should be indicated in all Spitzoid lesions with asymmetric dermoscopic images, dermoscopic features of melanoma and in children older than 12 years.
