The difference between flat warts and common warts lies in the clinical manifestations, the specific diagnosis and treatment should follow the doctor’s advice. The actual warts are usually smooth, round or oval flat papules, which appear suddenly and are numerous and dense, mostly on the face, the back of the hands and forearms and other exposed parts of the body, and there are no conscious symptoms, and occasionally there is a mild itching. The skin lesions of common warts are rough and irregularly shaped solid papules, which can gradually increase in size from the head of a pin and are found on the fingers, backs of the hands, and edges of the feet, and bleed easily when rubbed or bumped. If you are suspected of having flat warts or common warts, it is important to have a clear diagnosis and standardized treatment under the guidance of a doctor. The actual warts can be found in a number of different ways.
