Abstract：
Breast cyst, especially galactocele is usually benign. Needle aspiration or surgical removal are both diagnostic and therapeutic. Mastectomy is not necessary even if the whole breast is affected, but surgeons need to be vigilant. We describe a rare case of persistent and large breast cyst.
摘要：
乳腺囊肿,尤其是半乳囊肿通常是良性的。针吸或手术切除既是诊断性的，也是治疗性的。乳房切除术是不必要的，即使整个乳房受到影响，但外科医生需要保持警惕.我们描述了一种罕见的持续性和大乳腺囊肿。
