Nipple discharge and breast lump related to Montgomery's tubercles in adolescent females

Abstract

Four adolescent girls, aged 12 to 14 years, were seen for evaluation of spontaneous nipple discharge, two of whom had associated breast lumps in the ipsilateral breast. Clinical examination showed the discharge to be arising from one or several of Montgomery's areolar tubercles, with the breast lumps localized to the subareolar region immediately beneath the discharging tubercle. The secretions were episodic, thin, varied in color from clear to brown, but were not milky. All discharges resolved within 3 to 5 weeks, and the associated breast lumps resolved within 4 months without treatment. There were no associated clinical complaints or physical findings and detailed endocrinologic assessments including serum prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid function tests, and 17 beta estradiol; they were all normal. None of these patients was pregnant, and follow-up from 4 to 18 months did not reveal evidence of recurrence or other pathology. Experience gained from these four cases suggests that cysts and spontaneous, non-milky discharge related to Montgomery's tubercles in otherwise healthy, nonpregnant adolescent females, represents a benign, self-limiting problem. Unless other indications are present, endocrinologic investigation is unnecessary and spontaneous resolution can be expected.
