title: Small-bowel neuroendocrine tumor and retroperitoneal fibrosis: efficacy of octreotide and tamoxifen.
abstract: OBJECTIVE
  Neuroendocrine tumors are uncommon clinical entities and only a few cases of the co-occurrence of neuroendocrine tumors and retroperitoneal fibrosis have been described in the literature.
  
  
  METHODS
  We report the promising results achieved in a case of neuroendocrine tumor complicated by retroperitoneal fibrosis causing right ureteral obstruction treated with long-acting release octreotide and tamoxifen.
  
  
  CONCLUSIONS
  The treatment resulted in a complete response without toxicity.
