Abstract
Spitz neoplasms are relatively uncommon melanocytic lesions characterized by an epithelioid or spindled cell morphology and present more commonly in younger age. They represent a spectrum from benign to malignant lesions which sometime represent a diagnostic conundrum. Recent advances in the genetic characterization of these lesions allow a better classification with consequent improvement in diagnostic accuracy and patient management. This review aims at summarizing our recent understanding of these lesions at the molecular level.
