Intracystic lesions of the breast prove to be benign more often than malignancy, most intracystic lesions are benign papillomas. Generally sizes of cysts that contain papilloma are small. Relatively cysts that contain papillary carcinoma are large. A papilloma in a large cyst of the Breast is rare.
We report a rare case of a papilloma in a large cyst of the breast that presented a painless palpable mass. A 53-yr-old woman noticed palpable mass in her right breast. Ultrasonography indicated a 7 × 7 cm sized large cyst. There is a 2 × 2.5 cm sized hyper-echoic, polypoid mass in the cyst. On fine-needle aspiration was not obtained malignant cells. Excisional biopsy was done. Pathologic finding was papilloma.
Tumors in a large cyst of the breast is difficult in distinguish benign from malignancy by preoperative imaging, cytological and histological study.
Excisional biopsy should be performed before cancer surgery such as mastectomy to manage the cysts with intracystic growths.
乳腺囊内病变被证明为良性的情况比恶性更为常见，大多数囊内病变是良性乳头状瘤。一般来说，含有乳头状瘤的囊肿尺寸较小。相对而言，含有乳头状癌的囊肿较大。乳腺大囊肿内的乳头状瘤较为罕见。
我们报告一例罕见的乳腺大囊肿内乳头状瘤病例，表现为可触及的无痛性肿块。一名53岁女性发现右乳有可触及肿块。超声检查显示一个7×7厘米大小的大囊肿。囊肿内有一个2×2.5厘米大小的高回声、息肉样肿块。细针穿刺未获取到恶性细胞。进行了切除活检。病理结果为乳头状瘤。
乳腺大囊肿内的肿瘤通过术前影像学、细胞学和组织学研究很难区分良性与恶性。
在进行乳房切除术等癌症手术之前，应进行切除活检以处理有囊内生长物的囊肿。
