Dieulafoy disease of the stomach presenting as mass lesion--a case report. Indian Journal of Pathology & Microbiology. 2005 Apr; 48(2): 211-3http://imsear.searo.who.int/handle/123456789/75619Dieulafoy disease is a rare cause of severe gastrointestinal haemorrhage. The lesion is usually located in the stomach, although it may occur anywhere in the gastrointestinal tract. It is characterized by severe bleeding from a minute submucosal arteriole that bleeds through a punctate erosion in an otherwise normal mucosa. We describe a 55 year old patient of severe upper gastrointestinal bleeding caused by a gastric Dieulafoy disease, presenting as a mass lesion in the stomach, diagnosed clinically and radiologically as gastrointestinal stromal tumour. Increased awareness and early endoscopy are important for accurate diagnosis.engArteries --abnormalitiesDiagnostic ErrorsEndoscopyFemaleGastric Mucosa --blood supplyGastrointestinal Hemorrhage --diagnosisGastrointestinal Stromal Tumors --diagnosisHumansMiddle AgedStomach --blood supplyCase Reports
