text: The word melanoma has a long history of being used in a broader sense to refer to any melanocytic tumor, typically, but not always malignant, but today the narrower sense referring only to malignant types has become so dominant that benign tumors are usually not called melanomas anymore and the word melanoma is now usually taken to mean malignant melanoma unless otherwise specified.
