Gangliocytic paraganglioma of the duodenum.
In spite of possessing microscopic features of invasiveness, the clinical behaviour of duodenal gangliocytic paraganglioma is benign. The operation of choice for removal of the tumour is local excision. This conservative approach was used in the case of a 70-year-old white women who presented with occult gastrointestinal bleeding. The unusual histologic features of this woman's tumour are discussed. Although the tumour appears to be aggressive no recurrence has been reported to date following adequate local excision of a duodenal gangliocytic paraganglioma.
