Abstract
A case of squamous cell carcinoma of the tongue in a 26-year-old man developing nine years after renal transplantation is presented. This is the first such case to be reported. Within seven months, widespread tumor metastases resulted in death. Pathologic examination of the transplanted kidney demonstrated neither re-establishment of glomerulonephritis nor evidence of rejection, and lack of significant renal disease was confirmed by electron microscopy. This long term survival without development of renal pathology is also of great interest.
