That tiny dark spot on your foot could be more than just a freckle. Malignant melanoma is one of the most serious forms of skin cancer, and although it most often appears on sun-exposed areas, the foot is actually the most common site on the lower extremity. Catching a suspicious skin lesion early can make all the difference in protecting your health and your mobility.
At Sweeney Foot & Ankle Specialists, Dr. D. Sean Sweeney, DPM, FACFAS, and Dr. Christy Leahey, DPM, FACFAS, bring more than 20 years of trusted experience evaluating pigmented lesions of the foot and ankle. Voted Best Podiatrist in The Woodlands by Living Magazine every year since 2012, our team blends compassionate care with advanced diagnostic expertise to help you feel confident about every step.
What Is Malignant Melanoma of the Foot?
Malignant melanoma is a potentially deadly pigmented skin cancer that can develop anywhere on the body, but the foot and lower leg are surprisingly common locations. It can also form under the toenails or fingernails, with the big toe and thumb most often affected. Because foot lesions are easy to overlook, melanoma here is sometimes mistaken for a bruise, a fungal infection, or even gangrene — delaying the correct diagnosis.
Warning Signs to Watch For
Any new pigmented spot, or one that begins to change, deserves a professional evaluation. Subtle changes may develop slowly over months and can include:
- Increased size or deeper, darker color
- Uneven coloring — brown, bluish-black, or black patches
- Bleeding, oozing, or clear fluid seepage
- Tumor formation or ulceration of the skin
- Smaller “satellite” pigmented spots forming nearby
- A dark streak or discoloration beneath a toenail, especially the big toe
When a melanoma forms under a nail, the surrounding skin is often ulcerated and may be misdiagnosed as a fungal infection for months. If antifungal treatment isn’t working, a closer look is warranted.
How Melanoma Is Diagnosed and Treated
Diagnosis begins with a careful in-office examination of the lesion, your medical history, and any recent changes you’ve noticed. If melanoma is suspected, a biopsy is performed to confirm the diagnosis and determine the depth of the lesion, which guides the next steps. Treatment may involve surgical excision and coordinated care with dermatology or oncology specialists when needed. Early detection dramatically improves outcomes, which is why prompt evaluation matters.
