[A case of skin cancer diagnosed 21 days after renal transplantation]

The patient was a 67-year-old man who was started on peritoneal dialysis for treatment of diabetic nephropathy in March 2010. He received an ABO-compatible living-donor kidney transplant from his wife in October 2010. The immunosuppressive regimen consisted of tacrolimus, mycophenolate mofetil, steroid and basiliximab. Before the operation, a bump on his forehead/temple region that was increasing in size for years was noted. The bump had a scaly surface and the top of the bump was sloughed on postoperative day 14. Histological examination suggested malignancy. On postoperative day 21, a skin biopsy was performed by dermatologists and squamous cell carcinoma was confirmed. On postoperative day 36, wide excision and transposition flap procedures were performed by the plastic surgeon. At 15 months after transplantation, the kidney graft was functioning well with a serum creatinine level of 0.84 mg/dl and there was no sign of recurrence of the squamous cell carcinoma.
