[Metastases in the hypophysis]

Among 1521 malignant extracranial tumours, 64 metastases (4.2%) were found in the pituitary. The most frequent occurrence was found for carcinomas of the breast (21.4%) and for bronchial malignomas (5.9%). A statistically significant difference with regard to the location in the anterior and the posterior lobe was not found in our own patients. A remarkable fact is the high degree of affection of the pituitary gland in case of malignant melanomas.
