[A giant cancer of a gastric diverticulum].

An observation is presented, of a female patient aged 62 years with a large abdominal tumour. Clinical and para-clinical examinations could not establish the organic origin of the formation. Surgery disclosed a giant tumour developed in a gastric diverticulum situated under the cardia. The patient had suffered for a long time with gastric symptoms and her antecedents included upper digestive haemorrhage which was attributed to gastric ulcer according to radiological examination. In retrospect it was established that the disturbances were determined by a gastric diverticulum, complicated by haemorrhage and which later on had become malignant. In spite of its extraordinarily large size the tumour was removed by total gastric resection, in an attempt to treat radically the cancer.
