RESUMO
CONTEXT: Angiofollicular lymph node hyperplasia or Castleman's disease is a rare clinical condition. Knowledge about etiology and physiopathology; and treatment management as well are yet to be defined. Unicentric presentation of this disease affecting single lymph nodes in the mediastinum seems to be the most common presentation. Castleman's disease localized in the pancreas topographic area that mimics a pancreatic neoplasm is an even more uncommon event, with available published data of less than 15 cases until now. CASE REPORT: We present a 64-year-old male patient with a six-month past history of asthenia, adynamia, and lack of general clinical conditions. Imaging studies showed a nodular hypoechoic mass in the pancreatic head. Enucleation of the lesion was performed. Histopathological study revealed unicentric form of Castleman's Disease. CONCLUSIONS: Castleman's disease mimetizing pancreatic tumor is uncommon and it also curses with a difficult preoperative diagnosis. Surgery seems to be the best therapeutic alternative for this disease.

INTRODUCTION: Poor vascular access due to previous surgery can be a major obstacle in pancreas transplantation for which new exocrine and vascular outflow techniques might be useful. A 34-year-old female with early onset type 1 diabetes who underwent living donor kidney transplantation 20 years ago and a failed pancreas transplantation 2 years ago presented for pancreas retransplantation. METHODS: The inferior vena cava was used in the previous deceased donor pancreas transplantation and both iliac arteries had intense perivascular fibrosis, making arterial anastomosis impossible. The only remaining option for the implant was the infrarenal aorta, with venous drainage to the superior mesenteric vein and exocrine drainage to the gastric antrum. RESULTS: The patient had an uneventful recovery and graft function appeared normal. This report shows that when the recipient's abdominal cavity does not provide clear access for the usual surgical techniques regarding exocrine drainage, the stomach drainage procedure is an option. CONCLUSION: Duodenum-stomach anastomosis might be an alternative to portal enteric drainage because there is easy access for graft biopsies and even for procedures involving the papilla major.
