Warts & Viral Lesions
Warts and other viral skin lesions are caused by the human papillomavirus (HPV), which infects the top layer of skin and triggers excessive cell growth. Warts can appear on the hands, feet, face, or genital area and are contagious through direct contact.
At The Medical Group of New Jersey, our dermatologists offer safe, effective treatments to remove warts, prevent recurrence, and protect surrounding healthy skin.
Symptom Onset & Initial Evaluation
Symptoms depend on the type and location of the wart:
- Common warts: Rough bumps, usually on fingers, hands, or elbows
- Plantar warts: Hard, sometimes painful growths on the soles of the feet
- Flat warts: Small, smooth lesions on the face, arms, or legs
- Genital warts: Soft, flesh-colored bumps in the genital area caused by certain HPV strains
During your visit, your dermatologist will examine the lesion and review your history to determine the type of wart and whether the immune system or other factors may be contributing to recurrence.
Diagnosis
Diagnosis is clinical, based on the appearance of the wart. Occasionally, your dermatologist may recommend:
- Dermoscopy: Magnified examination for atypical lesions
- Skin biopsy: If a lesion looks suspicious or does not respond to treatment
- HPV typing or STD testing: For genital lesions requiring specialized care
Treatment & Ongoing Management
Treatment focuses on destroying infected tissue, stimulating the immune response, and preventing recurrence of the infection. Options may include:
- Cryotherapy: Freezing the wart with liquid nitrogen (most common treatment)
- Topical medications: Salicylic acid, imiquimod, or cantharidin to peel or trigger immune clearance
- Laser therapy or electrosurgery: For stubborn or resistant warts
- Immunotherapy: Injections or topical agents that boost local immune response
Your dermatologist will also provide instructions to avoid spreading the virus, such as not picking at warts, keeping the area dry, and wearing footwear in public places.
Follow-Up & Outlook
Most warts resolve within a few treatments, though some may recur. Regular follow-up ensures complete removal and early detection of new lesions. With proper care and immune support, most patients achieve full clearance and healthy, wart-free skin.
