Some might say that celebrities are over-exposed to the spotlight. And per our recent post on tanning, we’re seeing some celebs at least starting to minimize their over-exposure to sunlight (though sunless tans still abound), which helps raise awareness for skin cancer. Even the the legendary Bob Marley died from a cancer whose primary source was an acral melanoma under one of his toe nails. 
Rare but tricky to spot sometimes, Acral melanoma accounts for about 5% of all diagnosed melanomas. It is, however, one of the most common forms of melanoma in Asians and people with dark skin, accounting for up to 50% of melanomas that occur in people with these skin types. (And this is very important since recent studies have shown that Hispanics and African Americans tend to delay seeking diagnosis or treatment.)
Acral melanoma is often referred to as a “hidden melanoma” because these lesions occur on parts of the body not easily examined or not thought necessary to examine. It develops on the palms, soles, mucous membranes (such as the lining of the mouth, nose and female genitals) and underneath or near fingernails and toenails.
Here is what it usually looks like on each area of the body:
Palms of hand or soles of feet: Melanoma usually begins as an irregularly shaped tan, brown or black spot. It can be mistakenly attributed to a recent injury.
Under a nail: The first sign may be a “nail streak” – a narrow dark stripe under the nail. A new nail streak not associated with recent trauma, an enlarging nail streak, a wide or very darkly pigmented streak, or a nail that is separating or lifting up from the nail bed should be examined by a doctor.
NB: Acral melanoma can also develop without any obvious nail streak – particularly the non-pigmented variety.
Include these areas in your skin self-exams especially during a celebrity-style manicure or pedicure!
