Please add "myxoma" as a new category under Malignancy->Soft Tissue/Sarcoma Carl-Ludwig: did upload the original article, now correct paper.; added HLA typing as method to identify donor origin as this may be helpful as mehtod too.; agree to Michael
Expert comments for publication: 
These are benign lesions that occur most commonly in the left atrium. They do have the possibilities of embolization or mitral valve obstruction. Recurrence rate is estimated at 3% following excision. Since this lesion arose 13 years after transplant, it can be considered to have arisen from donor tissue (donor-derived) but most likely was not transmitted at the time of transplant.
