Abstract
A markedly-increased incidence of malignancy in renal allograf t recipients has been recognized in the forefront countries of transplantation. Recently, a clinical concern about the occurrence of malignancy after renal transplantation has arisen as the rate of long-term graft survival has improved in Japan.
This paper describes a case of multiple malignant lymphomas occurring in the gingiva 7 years after renal transplantation. A 45-year-old male complained of gingival painless swelling. Clinically, gingival hyperplasia induced by cyclosporin was diagnosed so gingivoectomy was performed.
Microscopic findings indicated malignant and diffuse lymphoma of pleomorphic type (LSG) .
