Objective.  —To report the development of metastatic prostate cancer in a heart transplant recipient without a primary focus in the recipient prostate gland; to present genetic evidence suggesting transplantation of the malignancy from the donor.

Design.  —Histological analysis of donor prostate and recipient prostate and rib. Molecular genetic analysis of prostate and kidney tissue from the donor and peripheral blood leukocytes and rib tissue from the transplant recipient.

Setting.  —University of Pennsylvania Medical Center.

Results.  —Multiple biopsies of recipient prostate were negative for malignancy but recipient rib contained prostatic adenocarcinoma with osteoblastic bone response. Molecular genetic analysis of recipient rib specimen, which contained both histologically normal and neoplastic cells, was shown to contain a combination of alíeles from the donor and recipient at 4 loci.

Conclusion.  —Although this is a single case report of an uncommon event, genotyping of polymorphic dinucleotide repeat elements from 4 different chromosomal regions provides strong evidence that the tumor cells arose from donor tissue and were transplanted along with the cardiac allograft.
