Pyogenic granuloma of the duodenum as an unusual cause of gastrointestinal bleeding

Pyogenic granuloma after embolization of a duodenal arteriovenous malformation in a patient with bleeding of obscure origin

“…Pyogenic granulomas are lobular capillary hemangiomas, usually found on the skin and oral mucosa, and are rare in the gastrointestinal tract, especially in the small intestine. [1][2][3] Its etiology is theorized to be in response to trauma or chronic irritation, such as infection. 2 On endoscopy, pyogenic granuloma shows as a polypoid lesion with a reddish surface, and is an uncommon diagnosis in patients with digestive hemorrhage of obscure origin or chronic anemia.…”

“…2 On endoscopy, pyogenic granuloma shows as a polypoid lesion with a reddish surface, and is an uncommon diagnosis in patients with digestive hemorrhage of obscure origin or chronic anemia. [1][2][3][4][5] Its treatment can be endoscopic or surgical resection. In the gastrointestinal tract, mucosal damage and exposure to gastric acid are reportedly a cause of pyogenic granuloma, and although there are some case reports in the small intestine, to the best of our knowledge, there are no reports on its appearance after embolization of a vascular lesion in the small intestine.…”
