Florid Keratoacanthomas in a Ktdney Transplant Recipient

Abstract
A 58-year-old man underwent renal transplantation. 8 years later the graft still functioned well. He has had immunosuppressive therapy, but in recent years only in low doses. Four years ago skin tumours started to appear and have been removed on 15 occasions. Most of the tumours were florid keratoacanthomas and their relation to immunosuppression is discussed. Examination of removed specimens by electron microscopy has not revealed the presence of virus particles in the cells.
