title: Primary Intestinal Hodgkin Lymphoma Mimicking Intraabdominal Abscess in a Renal Transplant Recipient: A Case Report.
abstract: BACKGROUND
  Post-transplant lymphoproliferative disease (PTLD) comprises a variety of lymphoid and plasma cell disorders arising in patients with a solid organ transplant. Monomorphic lymphomas represent the most significant part of this wide spectrum, with the overall risk rising with the aggressiveness of lymphoid proliferation in comparison to the general population. The development of Hodgkin lymphoma is very rare in transplant recipients, comprising less than 6% of all monomorphic PTLD, while cases of primary intestinal Hodgkin lymphoma in these circumstances are anecdotal.
  
  
  METHODS
  We describe an exceptional case of intestinal Hodgkin lymphoma mimicking an intra-abdominal abscess that developed in a transplant recipient 19 years after kidney transplantation. By presenting this case, we wish to emphasize the importance of suitable diagnostic pathways in transplant recipients experiencing prolonged fever episodes or masses of unknown origin, thus raising the awareness of possible PTLD development in such patients.
  
  
  CONCLUSIONS
  The lack of information about transplant recipients with Hodgkin PTLD regarding the site of involvement and type of treatment suggests the necessity of conducting larger international studies aimed at providing further insight into this particular group of patients.
