问题 单项选择题 A2型题

女性,48岁,右乳腺发现一无痛性肿块1月余,肉眼观察,肿物结节状,边界清楚,无包膜,切面为实性分叶状,并见弯曲的裂隙;镜下腺上皮细胞和肌上皮细胞呈裂隙状排列,裂隙周围间质富于细胞,并呈叶状突入腺腔;间质细胞异型性小,分裂象罕见,该患者最可能的诊断是()

A.乳腺良性叶状肿瘤

B.乳腺纤维腺瘤

C.乳腺纤维囊性乳腺病

D.乳腺积乳囊肿

E.乳腺盲管性腺病

答案

参考答案:A

解析:

绝经期女性,肿块切面见有裂隙的分叶状肿块,镜下可见两层上皮细胞围成裂隙,裂隙周围是间质细胞的增生,并呈叶状突向腺腔,形成分叶状结构,同时间质细胞温和,符合良性叶状肿瘤的特点。乳腺纤维腺瘤多发生在年轻女性,切面一般无裂隙,腺体和间质一起增生,形成包膜完整的肿块。乳腺纤维囊性乳腺病和乳腺积乳囊肿可见扩张的导管或导管呈囊性,间质细胞无明显增生。乳腺盲管性腺病大体检查病变边界不清,同时镜下以小叶扩大、腺泡囊性扩张为特点。因此正确答案为A。
