[Lymphoproliferative disease and cancer in the transplant patient].

According to the Spanish Cardiac Transplantation Registry, malignant neoplasm remain the fifth leading cause of death in heart transplant recipients. Skin cancers are the most common malignancies and they are frequently associated to solar keratosis, warts and keratoacanthoma. Geographic areas are high cumulative ultraviolet exposure have a greater incidence of skin cancer. Skin tumors are often located in chronically sun-exposed areas of the body. Lymphoproliferative disorders are the second most frequent malignant neoplasm after heart transplantation. Incidence of lymphoma is 350 times greater in heart transplant recipients than in the general population. B-cell tumors are the most common histologic type and it is associated with infection by the Epstein-Barr virus. T-cell tumors account for a 12% of all lymphoproliferative diseases and are not related to viral infections. Kaposi's sarcoma is the thirth commonest neoplasm in heart transplant recipients. Other malignat tumors are: uterine cervix, vulva, scrotum, colon, stomach, kidney and biliary tract. Prevention of neoplasm in heart transplant recipients include a decrease of immunosuppression and the avoidance of multiple immunosuppressive drug association. Some cases of neoplasm regression have been described when immunosuppressive therapy is decreased.
