目的 :探讨乳腺叶状囊肉瘤的病理特征与临床诊断以及治疗和预后的关系。方法 :对 33例经病理证实的乳腺叶状囊肉瘤 ,根据间质细胞异形程度和核分裂数、是否浸润、是否含有特殊间质成分进行分级。结果 :Ⅰ级 8例 ,Ⅱ级 16例 ,Ⅲ级 9例。Ⅰ级复发 3例误诊 6例 ,Ⅱ级复发 2例误诊 9例 ,Ⅲ级复发 5例误诊 7例。 7例含特殊间质成分。结论 :乳腺叶状囊肉瘤易误诊和复发 ,应与巨纤维腺瘤和乳腺癌鉴别。
Objective: To investigate the relationship between pathological features of breast cystosarcoma and clinical diagnosis, treatment and prognosis. Methods: Thirty-three cases of pathologically confirmed cystosarcoma of the breast were classified according to the degree of stromal cell abnormalities and mitotic numbers, whether infiltrated or not, and whether they contained special interstitial components. Results: I grade in 8 cases, Ⅱ grade in 16 cases, Ⅲ grade in 9 cases. Grade Ⅰ recurrence in 3 cases misdiagnosed in 6 cases, grade Ⅱ recurrence in 2 cases misdiagnosed in 9 cases, grade Ⅲ recurrence in 5 cases misdiagnosed in 7 cases. 7 cases with special interstitial components. Conclusion: The cystosarcoma of the breast is easy to be misdiagnosed and recurred. It should be differentiated from the giant fibroadenoma and breast cancer.
