Malignant carcinoid tumor of the anterior mediastinum metastasis to a prolactin-secreting pituitary adenoma: a case report.
BACKGROUND
Although the pituitary gland is known to harbor metastatic deposits, metastasis from a carcinoid tumor is extremely rare. Metastasis to a pituitary adenoma also is an infrequent occurrence.


METHODS
A case of malignant carcinoid tumor of the anterior mediastinum with metastasis to a prolactin-secreting pituitary adenoma is presented in this 46-year-old woman. This metastatic pituitary tumor demonstrated a high proliferative potential.


CONCLUSIONS
To our knowledge, this case represents the first documentation of metastasis from a malignant carcinoid tumor to a pituitary adenoma.
