病史摘要:
女性患者王X 30岁
主诉:无意间发现右侧乳晕下一包块.
外科情况:右侧乳晕下可扪及一3.0X3.0大小的包块,边界清,活动度尚好。
B超:发现右侧乳晕下可见一29mmX28mm液性暗区,边界清晰。
临床诊断:右侧乳腺囊肿
常规消毒下行细针吸取穿刺,抽吸出约7毫升淡咖啡色液体。全部离心,取试管底部沉淀物常规涂片、制片。HEX5
以下是引用海上明月在2010-5-31 18:22:00的发言:
请教:乳晕下几近3cm的囊性肿块,针吸出7ml液体,诊断乳晕下纤维囊性乳腺病是否合适? 大汗腺化生是肯定存在的;细胞簇团的结构和细胞形态没有异型性,所以是良性的,也基本可以考虑;是伴大汗腺化生的囊性增生性病变,还是囊性伴大汗腺化生的肿瘤?有待组织学证实。 |
提得很好。
关于这一例我报告是:考虑为纤维囊性乳腺病合并大汗腺化生,还是稍留有一些余地的。
还有其他的病变,就是散在的顶浆分泌的泡沫细胞,慢性炎性细胞。不仅只是大汗腺化生及形成假乳头样突起的形态表现。
这类纤维囊性乳腺病可能不止一个囊,可能还有微囊及卫星囊存在,也有纤维结构不良表现;它的特殊性在于临床上只表现为“孤立或单纯性囊肿”。
这例关键是能提示它是乳腺的良性增生性病变即可。如果报告导管乳头状瘤是需要接受进一步造影探查,甚至手术探查的。这个部位首要的鉴别诊断就是导管乳头状瘤、派杰氏病,但它们各自都有比较典型的临床特征和镜下形态学特点的。
谢谢。

Interesting case and thank for sharing.
I once did a lot of breast FNA when I was cytofellow at USC where all breast mass lesions would be referred to cytopathologists to do FNA. Now days FNA is rare to be used for the primary evaluation of breast lesions at Magee and most large medical centers in the US. If we do not consider the money, cost-effect, it will be easy for pathologists to read breast core bx than FNA.
For this case I woud like to sign out:
-Negative for maligancy.
-clusters of apocrine cells.
-Suggestive of fibrocystic changes.
Comment:
Mostly it is a lesion with cystic papillary apocrine metaplasia even though the papillary lesion cannot be completely excluded.
FNA combined with clinical impression and imaging finding (Triple test) is highly accurate. If one of the parameters is discordant, surgical biopsy is warranted. Benign Triple test should return for follow up in 3 to 6 months. (write this part in your comment for all FNA breast cases to protect yourself).
In fact 3 cm cystic lesion should be excisioned. Of cause I will not write this sentence in my report. Pathologists do not need to take all the responsblity for patient care. We take care of the part we should have.

GO ON.

Highly complex papillary apocrine change, high power.

Highly complex papillary apocrine change, low power.
Even at low power, the low nuclear to cytoplasmic ratio is readily apparent along with the uniform cell size and hints of decapitation secretions. The vacuolated cytoplasm and decapitation secretions along with the bland nuclear features are characteristic.
