"The key to recognition of melanoma is color . . . Irregular pigmentation with shades of blue-black, red, white and brown occurs. The skin markings are often disturbed, and the border is irregular. Satellite lesions, nodule, ulceration, bleeding, recent changes in size or color and diffusion of pigment into normal skin are other signs of melanoma."

Brief critique

 
The notion that common colors of melanoma are "blue-black, red, white, and brown" is fallacious. Macules of melanoma usually are characterized by nuances of brown. Even more elevated lesions of melanoma generally are devoid of blue, black, red, and white. In short, color often is not the key to recognition of melanoma; the key is a constellation of morphologic findings, only one of which is color. The word "irregular" for pigmentation and for the border of a lesion is confusing because no lucid definition of "regular" has ever been set forth. By the time that satellite lesions, nodularity, ulceration, and bleeding have occurred, the melanoma almost always has metastasized.
