What are plantar warts?
Plantar warts are small growths that usually appear on the weight-bearing surfaces of your feet. They are caused by HPV (Human papillomavirus) which feeds off of tiny blood vessels in your feet. Plantar warts are usually flat lesions with a rough surface. At the center of the wart, tiny black dots serve as the blood supply to the wart itself. These warts can make it painful for anyone to walk on their feet. The warts are also contagious and should be treated upon discovery.
Plantar Wart Treatment in Frisco, Texas
Plantar warts are small, sometimes painful growths that develop on the bottom of the foot. They are caused by certain strains of the human papillomavirus (HPV), which can enter the skin through small cuts or breaks. Because pressure from standing and walking pushes plantar warts inward, they may become covered by thick callused skin and feel as though you are stepping on a pebble.
Plantar warts can occur individually or develop in clusters known as mosaic warts. Small dark dots may be visible within the lesion. These are tiny blood vessels and are one feature that may help distinguish a plantar wart from a corn or callus.
Diagnosing a Plantar Wart
Dr. Woojung Lee can often identify a plantar wart by examining the affected area. The overlying callused tissue may be carefully trimmed to reveal features of the lesion. If a growth has an unusual appearance, changes rapidly, bleeds, or does not respond to treatment, additional evaluation or a biopsy may be recommended to rule out another skin condition.
Plantar Wart Treatment Options
Treatment depends on the wart’s size, depth, location, duration, and response to previous care. Your age, health history, circulation, immune function, and the number of warts present may also influence the treatment plan.
Options available at Modern Podiatry may include:
• Debridement to remove thick callused tissue covering the wart
• Prescription-strength salicylic acid to gradually remove infected tissue
• Cryotherapy, which uses controlled freezing to destroy wart tissue
• Laser therapy for selected or persistent plantar warts
• Cantharidin or another blistering medication applied in the office
• Bleomycin injection for stubborn warts that have not responded to other treatments
• Surgical removal in carefully selected cases
Debridement can reduce pressure and help topical medication reach the lesion, but it may not eliminate the underlying viral infection when used alone. Dr. Lee may combine in-office treatment with a home-care program to improve the likelihood of clearance.
How Many Treatments Will I Need?
Some plantar warts respond after one to three office treatments, while larger, deeper, clustered, or long-standing warts may require additional visits. Cryotherapy and certain other treatments are commonly repeated at scheduled intervals. No treatment can guarantee that a wart will resolve within a specific number of sessions, and recurrence is possible because the virus may remain in nearby skin.
Treatment for Persistent Plantar Warts
If a wart does not respond to initial care, Dr. Lee may recommend a different treatment or a combination of therapies. Laser treatment, bleomycin injection, or surgical removal may be considered for selected persistent lesions.
Surgical removal provides immediate removal of the visible lesion but may leave a painful scar, particularly on a weight-bearing area of the foot. For this reason, the potential benefits, risks, recovery, and alternatives should be carefully considered before surgery.
Preventing the Spread of Plantar Warts
To reduce the risk of spreading or acquiring plantar warts:
• Avoid picking, scratching, or cutting the wart
• Wash your hands after touching the affected area
• Keep the feet clean and dry
• Do not share shoes, socks, towels, or nail-care instruments
• Wear sandals in public showers, locker rooms, and pool areas
• Avoid walking barefoot in communal spaces
• Cover the wart as directed during treatment
Schedule an evaluation at Modern Podiatry in Frisco if you have a painful growth on the bottom of your foot, are unsure whether it is a wart, or have tried home treatment without improvement.
