Abstract
A case of inadvertent transplantation of malignancy is presented in detail. The donor was a 36 yr old woman with an unsuspected disseminated carcinoma of lung and the renal and tumor transplant recipient a 53 yr old man. The transplanted tumor remained clinically silent and was discovered only at necropsy after the recipient''s death from ischemic heart disease. The phenomena of de novo primary and transferred (donor) malignancy in organ recipients, along with related immunological considerations, are briefly reviewed. With regard to the increasing frequency and variability of organ transplants, the routine clinical practice required to minimize the risk of these complications is re-emphasized, with additional recommendations.
