Galactorrhea secondary to chest wall surgery in an adolescent.

Although nonpuerperal galactorrhea in youth may be a sign of pituitary prolactinoma, the etiology may be benign and extensive neurologic or endocrinologic evaluation and treatment may be unnecessary. An 18-year-old female with an unusual but benign form of transient galactorrhea due to chest wall surgery is reported. It is hypothesized that the sectioning of the intercostal nerves may result in reflex stimulation of hypothalamic centers controlling lactation through the same neural pathways involved in puerperal lactation. The patient experienced galactorrhea for two months and transient amenorrhea. She is asymptomatic without galactorrhea at nine months follow up.
