Amelanotic melanoma is a type of skin cancer in which the cells do not make any melanin. [1]: 696 [2] They can be pink, red, purple or of normal skin color, and are therefore difficult to diagnose correctly. They can occur anywhere on the body, just as a typical melanoma can.

[165] In his later work in 1857 he remarked that there is a familial predisposition for development of melanoma (Eight Cases of Melanosis with Pathological and Therapeutical Remarks on That Disease).
The borders of these amelanotic melanomas are often indistinct, making visual identification without a dermatoscope very difficult. People with a personal or family history of skin cancer or of dysplastic nevus syndrome (multiple atypical moles) should see a dermatologist at least once a year to be sure they are not developing melanoma. [29]
