摘要

目的：

探讨伴大汗腺分化浸润性乳腺癌（invasive breast carcinoma with apocrine differentiation，BCAD）的超声特征。

方法：

回顾并分析14个BCAD病灶的临床及超声表现特点，总结其声像图特征。

结果：

14个BCAD病灶中，单纯性大汗腺癌（pure apocrine carcinoma，PAC）8个，混合性大汗腺癌（mixed apocrine carcinoma，MAC）6个，病灶多发生于外上象限（71.4%），且60.0%位于左乳外上象限。超声检查示BCAD可表现为实性低回声（64.3%）或囊实性回声（35.7%），其中50.0%的PAC为囊实性回声，而MAC以实性低回声为主（83.3%），PAC、MAC的形状多不规则（75.0%、83.3%），边缘均以成角为主（分别为62.5%、83.3%），多伴微钙化（分别为75.0%、50.0%），血供多为AdlerⅡ~Ⅲ级（分别为87.5%、66.7%）。BCAD的超声定性诊断与病理学检查符合率为78.6%。

结论：

BCAD发生的位置及声像图具有一定特殊性，但声像特征不典型，确诊仍需进一步行病理学活检。

Abstract

Objective:

To investigate the ultrasonographic features of invasive breast carcinoma with apocrine differentiation (BCAD).

Methods:

A total of 14 lesions of BCAD confirmed by pathological examination were selected to analyze the clinical and ultrasonographic features

and the sonographic characteristics were summarized.

Results:

Eight pure apocrine carcinomas (PACs) and six mixed apocrine carcinomas (MACs) were included in the 14 cases

and 71.4% cases occurred at outer upper quadr

ant and 60.0% on the left breast. Ultrasound examination showed that 64.3% lesions were solid hypoechoic and 35.7% showed complex echo

and 50.0% PACs were complex echo while 83.3% MACs showed solid hypoechoic. Most of PACs and MACs showed irregular shape (75.0% and 83.3%

respectively)

angular protrusion of edge (62.5% and 83.3%

respectively)

accompanied by calcification (75.0% and 50.0%

respectively)

and blood Adler Ⅱ-Ⅲ grade (87.5% and 66.7%

respectively). According to pathology results

the ultrasonic coincidence rate of BCAD was 78.6%.

Conclusion:

The sonographic findings and position of BCAD are certain particularity. Since sonography characteristic of BCAD is not obvious

the definitive diagnosis still requires pathological biopsy.
