Abstract

Although the relationship between immunosuppression and cancer risk is well-documented, the association between immunosuppression and the development of preneoplastic lesions (PNL) is less clear. PNLs pose a unique clinical conundrum in the transplanted pancreas because their prevalence in the general population is not infrequent. We present the case of a 58-year-old man with a history of diabetes mellitus type 1 who underwent successful pancreas transplantation with bladder drainage. His kidney function failed 13 years after his transplant and he developed recurrent painful hematuria with symptomatic anemia 2 years after initiating hemodialysis. Upon work-up, he was found to have a 4 cm intraductal papillary mucinous neoplasm in his pancreas allograft. At his enteric conversion, the intraductal papillary mucinous neoplasm was removed through a distal pancreatectomy due to concern for its malignant potential. He recovered well from surgery and continues to be insulin-free. With the rising incidence of PNLs from improved detection and the improved survival of pancreas allografts, the implications of PNLs may be more pronounced in the future. This case raises several important considerations for the pancreas transplant surgeon regarding adequate allograft surveillance protocols, treatment, and follow-up.
