Common Warts, also known as Verruca Vulgaris, is caused by non-malignant strains of human papillomavirus (HPV). They are typically benign lesions that rarely have malignant transformation. On the skin, they appear as rough, painless papules that can be grey or flesh-colored and are found on different body areas. Other subtypes of HPV that are associated with cervical cancer are not the same strains that cause verruca Vulgaris.
