RESUMO
The transplant renal artery stenosis occurred up to 23% after kidney transplantation. Endovascular treatment has become the treatment of choice of this complication, but could be challenging in immediate postoperative anastomotic narrowing. We report the case of a adolescent with early renal graft artery stenosis located in the anastomosis and diagnosed 3 days after renal transplantation, with necessity of haemodialysis. This complication was treated by angioplasty on the 25th day, using a polymer free drug eluting stent with a good result. We discussed the precautions and technical features of this procedure.

Castleman's disease is a rare lymphoproliferative disorder of unknown etiology with different clinical manifestations. A 76-year-old man presented with pruritus and jaundice, a cholestasis and an increase of acute phase reactants. Peroperative investigations evidenced a 3-cm lymphadenopathy that compressed the biliary duct. Diagnosis of multicentric Castleman's disease was confirmed by the histologic examination of the lymphadenopathy. HIV testing was negative. Corticosteroid therapy was started and partially controlled the disease.

Granulocytic sarcoma is a rare tumor composed of immature cells of the granulocytic series which usually occurs as a secondary manifestation of acute leukaemia. We report the case of a 60 years old woman without particular previous pathologies who was hospitalised for chronic diarrhea developed in a context of health impairment state. The blood cell count revealed severe leucopenia and thrombopenia; an emergency right colectomy was accomplished. The histologic examination showed granulocytic sarcoma of the ascending colon. The death occurred rapidly as a consequence of a toxic shock. This observation seems to be the sixth case report of the granulocytic large bowel sarcoma in the literature which likely complicated a pre-existant and unknown myeloid leukaemia.
