The expression is still used in its original sense, and means a retention cyst resulting from blockage of the duct in association with involutional changes, or with an hypertrophy and abnormal secretion.In the process of involution, a portion of the breast may fail to atrophy, and, with the continued activity of the epithelial cells lining the ducts and alveoli, a cyst may be formed. Subsequently, the epithelium of the structures outside the cavity may atrophy either |
