Flat wart - External and Internal Eye
The warts arise from benign strains of HPV and are not known to cause cancer. They are contagious and spread easily over the body. Transmission is commonly via person-to-person contact or via fomite. Existing skin trauma (ie, cuts, scratches, burns, eczema) predisposes patients to contracting HPV. A person with flat warts may spread the warts to a different part of the body (autoinoculation) through trauma to the skin such as scratching or shaving.
Children, young adults, and immunocompromised patients are most susceptible.
While warts are normally self-limited in children, they may be difficult to treat in adults. Longer periods of treatment are usually necessary for adults.
