Most pigmented lesions are actually moles and freckles but one
lesion to be very concerned about is malignant melanoma.
Melanoma can occur on the foot or lower extremity or may even
form under the toenails. Often the skin next to the nail
is ulcerated or has a wound. Actinic Keratosis is
another lesion on the feet that can be cancerous but are often
mistaken for warts.
Signs and Symptoms
Lesions that appear to be warts should be checked out by your
podiatrist. Be careful to watch for pigmented lesions that
appear suddenly or lesions that start to change
in appearance. Call your podiatrist immediatley if you
notice these changes.
Freezing of the lesions with liquid nitrogen or excision of the
lesion is often performed. The lesion may be sent to a
lab to detemine if it is cancerous.
