Background: As the number of long-term survivors after organ transplantation increases, malignancy has become a problem as a late complication. We herein report a case of endometrial cancer during the follow-up of pancreas transplantation after kidney transplantation.
Case presentation: A 49-year-old woman was diagnosed with endometrial cancer. The patient had developed type 1 diabetes at 8 years old and started insulin treatment, and at 29 years old, she started hemodialysis for diabetic nephropathy. At 31 years old, she received living donor kidney transplantation and withdrew from dialysis. Hypoglycemia unawareness began to occur frequently from around 36 years old, and at 48 years old, the patient underwent deceased donor pancreas transplantation after kidney transplantation and achieved insulin independence. At 49 years old, she was diagnosed with endometrial cancer. Surgical treatment (total abdominal hysterectomy with left salpingo-oophorectomy) was performed. The pathologic diagnosis was confirmed as stage 1A uterine endometrioid carcinoma grade 1. The postoperative course was uneventful. She was discharged from our hospital on postoperative day 8. There has been no evidence of recurrence and/or metastasis of endometrial cancer for 16 months since the surgery.
Conclusions: Carcinogenesis after pancreas transplantation may be a lethal late complication. It is important to carry out regular screening examinations with carcinogenesis in mind.
