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).
Sometimes plantar warts can grow in clusters; those are called mosaic warts. Sometimes corns or calluses are mistaken for a palmer or plantar wart. In some warts, little black dots appear, leading people to call them seed warts. Actually the black dots are little blood vessels that have grown up into the wart.
