A Cameron lesion is a linear erosion or ulceration of the mucosal folds lining the stomach where it is constricted by the thoracic diaphragm in persons with large hiatal hernias. The lesions may cause chronic blood loss resulting in iron deficiency anemia ; less often they cause acute bleeding.
16 gen 2023 · Cameron lesions are a rare cause of upper GI bleeding that is localized to the gastric body mucosa of patients with large hiatal hernias. It causes occult bleeding and chronic iron-deficiency anemia. These lesions are often missed on initial endoscopy and can cause fatal complications.

Abstract. Cameron lesions are erosive-ulcerative alterations of gastric mucosa occurring in patients with large hiatal hernia, potentially causing gastrointestinal bleeding and iron deficiency anaemia. Diagnosis may be challenging, and not infrequently erosions are overlooked at endoscopy, so that repeated and unnecessary diagnostic procedures ...

Discussion Cameron's ulcers are a rare cause of upper GI bleeding and have been reported in up to 5 % of patients with HH who underwent routine EGD. The pathogenesis of these ulcers is likely multifactorial secondary to mechanical trauma to the gastric mucosa as the hernia slides through the diaphragmatic hiatus or due to the pressure-induced ...
21 set 2012 · Cameron lesions represent linear gastric erosions and ulcers on the crests of mucosal folds in the distal neck of a hiatal hernia (HH). Such lesions may be found in upto 50% of endoscopies performed for another indication. Though typically asymptomatic, these may rarely present as acute, severe upper gastrointestinal bleed (GIB).

30 nov 2021 · Cameron lesions refer to linear ulcers or erosions that occur on the mucosal folds at the diaphragmatic impression of a hiatus hernia. They are usually radiographically occult and diagnosed endoscopically (although still useful for a radiologist to know).
12 apr 2020 · Abstract. Cameron lesion is an uncommon cause of overt upper gastrointestinal bleed (GI bleed). Though hiatal hernia is a well-known entity, Cameron lesions that may occur in them are usually missed during upper endoscopy. Patient with Cameron lesions usually presents as chronic iron deficiency anemia, rarely as acute GI bleed.
