Various diagnoses of pigmented skin lesions, by relative incidence upon biopsy, and malignancy potential.

Evaluation

By their relative incidences, a practical approach is:

  • Is it a high-grade dysplastic (melanocytic) nevus or melanoma? If not:
  • Compare to patterns of various other possibilities.
