-[[File:Dark skin focalities.jpg|thumb|center|Dark skin focalities (in this case, from top left and clockwise: Spitz nevus, seborrheic keratosis, elevated melanocytic nevus and melanoma)]]
-Skin with one or more areas that are darker than the surroundings.
-===Microscopic evaluation===
-[[File:Pie chart of incidence and malignancy of pigmented skin lesions.png|thumb|370px|Various diagnoses of pigmented skin lesions, by relative incidence upon biopsy, and malignancy potential.]]
-Evaluation is largely based on the relative incidence and malignancy of various differential diagnoses (see pie chart). Main approaches are:
-*Direct pattern recognition
-*Systematic

-====Systematic====
-By their relative incidences, one practical approach is:
-*Is it a '''[[Dysplastic nevus|dysplastic (melanocytic) nevus]]'''? If not:
-*Is it a '''[[Melanoma]]'''? If not:
-*Compare to patterns of various other possibilities.
