Breast cysts lead the benign conditions of the breast problem. A 15-year-old girl admitted to our hospital with pain and swelling on the right breast. On physical examination, periareolar erythema in the presence of a tender subareolar mass on the right breast and non-Tender, smooth, non-fixated retroareolar mass on the left breast was prominent. Ultrasonographic evaluation identified an infected retroareolar cyst. Medical treatment was successful without any invasive intervention. First-line conservative management for infected cysts is antibiotheraphy. Every effort should be made to preserve the developing breast bud and drainage considered only in the rare presence of abscess formation unresponsive to antibiotics. Unlike adults, hormonal evaluation should be done in every girl. Multidisciplinary long term follow-up is crucial.
