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 can erupt anywhere on the sole of the foot. They may be difficult to distinguish from calluses. However, you may be able to see tiny black dots on the surface layer of a plantar wart. These are the ends of capillary blood vessels. Calluses have no blood vessels, usually resemble yellow candle wax and are located only over weightbearing areas. Plantar warts can be very painful and tender.
