Successful kidney transplantation in a patient with multiple endocrine neoplasia type 2A syndrome: case study.

We present the case of a 37-year-old patient diagnosed with multiple endocrine neoplasia type 2A (MEN 2A) syndrome, as confirmed by genetic tests, who underwent the transplantation of a kidney from a cadaveric donor. MEN 2A, a hereditary autosomal dominant syndrome, is caused by the mutation of the RET proto-oncogene. In almost all patients this syndrome, is characterized by the occurrence of medullary thyroid cancer and pheochromocytoma; in some individuals also hyperparathyroidism. The available literature has not documented a kidney transplantation performed in Poland for this indication.
