Demographic data only available for the spitz naevi group. No information on how the controls were selected. Authors state that the majority (14/19: 74%) of the FISH+ spitz naevi cases were characterised by positivity for two or three of the four diagnostic criteria, thus reducing the risk of misinterpretation.

Country Spain All cases of Spitzoid melanomas treated at one hospital assessed. N= 17. Comparator: Cases of spitz naevi from hospital files included. N = 6. Inclusion criteria: Not provided. Exclusion criteria: Two cases of Spitzoid melanoma excluded as the original biopsies could not be obtained, two because of doubts in the differential diagnosis and one because the Spitzoid area accounted for <25% of the biopsy specimen. N=5.
