Isolated galactorrhea with normal serum prolactin levels: clinical implications.
Detailed endocrine-metabolic studies were performed on five women who were otherwise well but who had had inappropriate breast secretions for variable periods of time (three months to 16 years). Our results suggest that the presence of a lactose-containing breast secretion, which strictly defines galactorrhea, does not necessarily indicate a recognizable abnormality if normal hypothalamic-pituitary function is present. In these regularly menstruating women with isolated galactorrhea, we suggest a minimum initial evaluation, but careful long-term follow-up studies to identify those cases which may progress to the other recognized, more serious amenorrhea-galactorrhea syndromes.
