• Importance Nodular melanoma (NM) is a rapidly progressing potentially lethal skin tumor for which early diagnosis is critical.

  Objective To determine the dermoscopy features of NM.

  Design Eighty-three cases of NM, 134 of invasive non-NM, 115 of nodular benign melanocytic tumors, and 135 of nodular nonmelanocytic tumors were scored for dermoscopy features using modified and previously described methods. Lesions were separated into amelanotic/hypomelanotic or pigmented to assess outcomes.

  Setting Predominantly hospital-based clinics from 5 continents.

  Main Outcome Measures Sensitivity, specificity, and odds ratios for features/models for the diagnosis of melanoma.
