Overview of Peptic Ulcer Disease Peptic ulcer disease (PUD) is a chronic (long lasting) condition that affects the gastrointestinal (GI) tract or digestive system. PUD causes ulcers (sores or lesions) in the lining (mucosa) of the stomach or first part of the small intestine (duodenum).
What are the symptoms and how are plantar warts diagnosed? These warts can look like small, fleshy bumps; hard, flat growths with a rough surface and well-defined boundaries; or gray or brown lumps with tiny pinprick-size black dots (clotted blood vessels that distinguish warts from bloodless corns and calluses).
Plantar warts, like other warts, are caused by human papillomavirus (HPV). But the type of HPV that causes plantar warts is not dangerous. However, because they are located on the soles of the feet, they may hurt when you stand or walk.lantar warts affect one part of the body: the foot. Plantar warts are rough, raised patches of skin, often with tiny black dots on the surface. They usually occur on the plantar surface -- the soles -- of your feet.
