[Association of lobular epithelioma and hypophyseal adenoma in a young woman. A case report].

The authors report the case of a 28 year old patient with a prolactin and somatotropin secreting pituitary adenoma who presented several months later with lobular carcinoma of the breast with lymph node metastases. This case raises the question of the role of prolactin and growth hormone in the pathogenesis and growth of breast cancer. It is noteworthy, in particular, because of the exceptional clinical manifestations.
