Table 12. . Modena algorithm: a reflectance confocal microscopy score for the diagnosis of malignant melanoma.
Criteria (score) | RCM feature |
---|---|
Major criteria (+2 points per feature) | Nonedged dermal papillae |
Atypical cells at the DEJ | |
Minor criteria (+1 point per feature) | Roundish pagetoid cells |
Pagetoid cells widespread throughout the lesion | |
Cerebriform clusters in the papillary dermis | |
Isolated nucleated cells within dermal papilla |
DEJ: Dermoepidermal junction; RCM: Reflectance confocal microscopy.
