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).
Common warts have a rough surface and well-defined borders. They are round or irregular in shape and usually range from 2 millimeters to 10 millimeters wide (the size of a pencil eraser or smaller). Common warts are firm and can be light gray, flesh-colored, yellow, brown or gray-black. They occur most often near the fingernails and on the backs of the hands, but they also can appear on the elbows and knees. Common warts usually do not hurt. Plantar warts appear on the bottom (sole) of the foot.
