Gastric and duodenal pseudomelanosis: a new insight into its pathogenesis
Very infrequently, gastric melanosis and pseudomelanosis have been described.1-6 Melanosis refers to melanin deposition, and pseudomelanosis is due to hemosiderin deposition. The etiology of these entities is poorly understood, and endoscopically, it is generally very difficult to differentiate between melanosis and pseudomelanosis. They are, likely, incidental endoscopic findings with minimal clinical significance. Gastric and duodenal pseudomelanosis manifests as speckled black pigmentation or black spots in the mucosa.Hemospray hemostasis in bleeding diffusely ulcerated esophagus
Bleeding from diffuse esophageal ulcerations can be difficult to treat. Hemospray is a hemostatic powder, and its mechanism of hemostasis is thought to be through concentrating clotting factors and forming mechanical plugs on bleeding vessels.
