Spitz nevi represent a distinct type of melanocytic nevi more commonly seen in childhood. Although typically benign, a subset of Spitz lesions raise concern and create a diagnostic dilemma as a result of confusing histology that involves characteristics of classic Spitz nevi intermixed with features of cutaneous melanoma. Such atypical Spitz lesions, or Spitzoid tumors of uncertain malignant potential, are difficult to classify and their biologic potential is uncertain. Nonetheless, these are critical tasks for both prognosis and clinical management. New tools, such as immunohistochemical stains, comparative genomic hybridization, and fluorescence in situ hybridization, have been used to provide further insight into these controversial lesions and to aid in their evaluation. In this review, we present our experience managing 6 cases of Spitzoid tumor of uncertain malignant potential and discuss the potential use of various diagnostic modalities, including sentinel lymph node biopsy, immunostaining, and molecular analysis.
