[Gangliocytic paraganglioma of the duodenum].

Gangliocytic paraganglioma in a female of 64 years of age with stones in the gall bladder, atrophic liver cirrhosis and gastro-intestinal polyposis is described in the Russian literature for the first time. Polyps of the rectum and sygmoid were removed within 15 years. The same pathology was described by other authors. It is possible that the occurrence of paraganglioma and polyps was of genetical nature. The tumor was detected at gastroduodenoscopy. Biopsy diagnosis varied from polymorphocell liposarcoma and malignant fibrous histiocytoma. Endoscopic tumor electroexcision was complicated by intestinal bleeding that followed by an urgent laparatomy, duodenotomy and suture of the bleeding vessel in the duodenal wall. Bleeding zone in the duodenum was 3 cm from papilla Vateri. Analysis of difficulties in clinical and morphological differential diagnosis is performed.
