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).
Similar in appearance are warts on the palms (palmar warts). Small warts growing in clusters on the plantar surface of the foot have been called mosaic warts. Flat (plane) warts may arise on the face, legs, and other parts of the body, often in large numbers. Periungual warts are warts around or under the nail.
