What Are Viral Verrucae Barton-le-Clay?
Certain strains of the human papillomavirus (HPV), a common virus that affects the skin, cause verrucae.
They typically develop on the soles of the feet and may appear as small, rough or hardened areas of skin. Some have tiny dark dots from small blood vessels.
Because verrucae develop in weight-bearing areas, walking or standing can sometimes make them uncomfortable.
Verrucae can vary in appearance and may occur individually or in clusters.
Not every skin growth on the foot is a verruca. Corns, calluses, and other skin conditions can look similar, so accurate identification is important before treatment.
