When the human papillomavirus infects the skin, a wart (or verruca) can form. This process creates a growing, painful lesion involving the soft tissue of the foot that can make walking and standing difficult. Most commonly found in children, these contagious lesions typically appear on the bottom (plantar surface) of the foot. They can develop as a single lesion or in a cluster (mosaic configuration) of many lesions growing together in one area. As the wart grows and the skin thickens, patients may see tiny black specks on the surface of the wart. These black specks are actually dried blood from underlying capillaries that feed the wart.
Following a thorough physical examination, your podiatrist will differentiate a wart from other skin conditions and will discuss potential treatment options, which may include topical or oral medications, laser therapy, injection therapy, and even surgical removal. It is important to follow the treatment plan set forth by your podiatrist to avoid transmission and spreading of the warts.
