Atypical Spitzoid neoplasms represent a controversial and incompletely defined diagnostic category for lesions with intermediate architecture and cytomorphology between Spitz nevus and melanoma. The vast majority of these neoplasms have a good overall prognosis. Only a small proportion of patients will end up developing distant metastases and death. The distinction between Spitz tumours with atypical features and Spitzoid melanoma remains difficult on clinical and histological grounds and the prediction of the biological behaviour of those tumours even with sentinel lymph node biopsy is impossible. Tools such as immunohistochemistry, genetic analysis, mutation analysis and mass spectometry have contributed to the better understanding of those tumours and may be useful in the differential diagnosis of Spitzoid tumours.
