Cameron lesions

Cameron lesions are linear gastric erosions positioned at the diaphragmatic impression, in patients with large hiatus hernia. It is a distinct entity from other erosions and was described first time about 20 years ago by AJ Cameron. Clinical significance: In upto one third of cases cameron lesions can present as acute upper GI bleed which may become life-threatening. Despite treatment, 33% develop recurrence of the lesion with possible acute event requiring immediate surgery. Lesion can also cause iron deficiency anemia and chronic GI bleed.
