Clinical disorders in patients with hyperprolactinaemia. Experience with 59 patients.

Fifty-nine patients with hyperprolactinaemia and presumed, or histologically proven, pituitary tumours were identified within a seven-year period. The wide variety of clinical presentation, the natural history, and the problems associated with therapy are highlighted in several selected case presentations which include both patients with invasive tumours and those with no radiological abnormalities and minimal symptoms. The special considerations involved in a planned pregnancy in a patient with hyperprolactinaemia are emphasized.
