The Clinical Spectrum of Cutaneous Melanoma Morphology

Melanoma can mimic many cutaneous lesions, impairing correct diagnosis. By clustering of diagnostic assignments, five common melanoma morphological groupings were identified: typical, nevus-like, amelanotic/NMSC-like, SK-like, and lentigo/lentigo maligna-like. Awareness of the diversity of melanoma appearances and their associated clinical factors may help dermatologists improve their diagnostic accuracy.
