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 are often similar to calluses or corns, but can be differentiated by close observation of skin striations. Feet are covered in skin striae, which are akin to fingerprints on the feet. Skin striae go around plantar warts; if the lesion is not a plantar wart, the striations continue across the top layer of the skin. Plantar warts tend to be painful on application of pressure from either side of the lesion rather than direct pressure, unlike calluses (which tend to be painful on direct pressure instead).
