title: Lactating Adenoma of the Breast.
abstract: Lactating adenoma is an uncommon breast palpable lesion occurring in pregnancy or lactation. Although it is a benign condition, it often requires core biopsy or even surgery to exclude malignancy. As with other solid lesions in pregnancy and lactation, lactating adenoma needs an accurate evaluation in order to ensure its benign nature. Work-up must include both imaging and histologic findings. Ultrasound evaluation remains the first step in assessing the features of the lesion. Some authors consider magnetic resonance imaging as a useful tool in cases of inconclusive evaluation after ultrasound and histologic exam in an attempt to avoid surgery. Most lactating adenomas resolve spontaneously, whereas others persist or even increase in size and must be removed. The authors present a case of a 35-year-old woman at 6 months postpartum with a lactating adenoma in her right breast. After surgical removal, breastfeeding was perfectly continued within the next 24 hours, which highlights the fact that breast surgery is most often compatible with breastfeeding.
