Kaposi sarcoma is one of the most frequent transplant related malignancies. It affects 1 in 200 transplant patients in the United States. This rate is 400 to 500 times higher than that seen in the general population.
A research team from Italy investigated Kaposi sarcoma transmission in 5 female organ recipients. The patients developed the disease after receiving organs from male donors.
The research team was able to confirm that the tumors in these patients
originated from the donor.

Previous studies have found that transplanted organs can transmit viruses. However, this study suggests that both viruses and virus-infected tumor cells can be passed on to an organ recipient.
Dr Mario Luppi's team stated that, "The results, while still preliminary, highlight the potential for transmitting harmful diseases through transplanted organs, and the need for organ pre-screening".
