Many patients present to the office with a newer onset "dark spot" on their foot or under their toenail.  They often times state that this has become larger, raised or changed in shape.  The dark spot is often located on the bottom of the foot, but patients also have noticed a darkened line under their toenails that do not seem to grow out with the growth of the toenail.  These spots or changes are often associated with melanoma in the foot.

Melanoma is a rare clinical entity in Caucasians, accounting for only 2 - 8% of melanoma cases in white patients. However, in dark-skinned ethnic groups of African-American, Asian, or Hispanic descent, melanoma arises on the plantar surface of the foot in 35–90% of patients diagnosed.  If caught early enough, melanoma can be cured.

In the foot and ankle, the area of suspicion can be biopsied to determine the depth and extent of the lesion.  This can help to determine the stage of this particular cancer.  Often, if problematic, the podiatrist can refer to an oncologist for further workup, like the melanoma may be elsewhere as well. If you have a suspicious spot on your foot or under your toenail, do not hesitate to make an appointment with Indiana Podiatry Group.  What you thought maybe a "mole" or a bruised toenail, may be more extensive or serious
