Primary bronchogenic carcinoma in the heart transplant recipient.

An increased risk of neoplasia is a well-recognized complication of chronic immunosuppression. Although lung cancer has been sporadically reported in the transplant population, it has not been recognized widely as a specific risk among heart transplant recipients. We present 3 cases of bronchogenic carcinoma in cardiac transplant patients, discuss possible risk factors, and outline recommendations for diagnosis and management of new lung lesions discovered during routine follow-up.
