大体所见 | (右卵巢)灰红色囊壁样组织一块,大小7*3*0.7cm,囊壁厚。01-0.3cm,囊内容物流失,囊壁触之有粘液感。 (左卵巢)灰红色囊壁样碎组织一堆,大小共计约5.5*5.5*1.5cm,囊壁厚0.1-1cm,部分囊壁内附直径0.5-1.3cm的透明小囊肿,囊内壁粘液感,部分囊壁内附着咖啡样物。 |
卵巢交界性粘液性囊腺瘤(肠型)。
卵巢交界性粘液性囊腺瘤:卵巢交界性粘液性囊腺瘤一般体积较大,呈囊性,常多房,囊内壁光滑,多数有乳头突起,囊内为粘液样物。显微镜下:囊壁被覆类似宫颈的粘液柱状上皮和(或)类似肠上皮,上皮有丛状矮乳头状生长,层次增多,但不超过4层,有轻度到中度异型性,无卵巢间质浸润,可有腹膜表面种植,但无种植处深部浸润。这种交界性肿瘤依其异型性程度又有低级别和高级别之分。

粘液性肿瘤,双侧发生,提醒临床排除转移,是个原则,要记住。特别是冰冻切片,术中要探查。
但本例有良性肿瘤成分和交界性成分的过渡,卵巢原发的可能性也是有的。还有一种很小的可能性,就是原有卵巢良性和交界性肿瘤又被转移癌累犯。

1. Benign cytomorphological features for most glands; some show mild atypia.
2. Some areas indicate infiltrating-lik growth pattern.
3. Significant Stains: Both CK7 and CK20 strongly and diffusely positive; Ki67 -low proliferative index.
4. It is not classic ovarian mucinous borderline tumor based on the morphology, growth pattern, and stains (ck7/20 positive)
5. Pick one dx: metastatic. Of cause primary cannot be completely excluded.
6. Suggest: CDX2, SMAD4 (ovarian tumors positive; 60% 胰腺/胆管cancer , 20-30% colon cancer negative), ER/PR/pax8 (more ovarian mucinous tumors, especially cancer and borderline will be negative. ER/PR/Pax8 positivity have diagnostic significance for ovarian primary. But the negativity of ER/PR/Pax8 cannot rule out ovarian primary.
7. Clinical correlation with imaging is recommended. Sometimes we cannot make the definite pathological dx. It is acceptable.

翻译:
1、大多数腺体呈良性细胞形态学特征,一些呈轻度异型性;
2、一些区域显示有浸润性生长模式;
3、重要的染色:CK7和CK20两者呈弥漫强阳性,Ki-67增殖指数较低;
4、基于形态、生长模式以及免疫组化染色(CK7和CK20呈阳性)特征,这一例并不是经典型卵巢黏液[***]界性肿瘤;
5、选择一个诊断:转移性。当然,也不能完全排除原发性;
6、建议:CDX2和SMAD4 (卵巢肿瘤呈阳性;60% 胰腺/胆管、 20-30%结肠癌呈阴性);ER/PR/pax8 (更多的卵巢黏液性肿瘤,特别是癌和交界性肿瘤呈阴性;ER/PR/Pax8 阳性对于卵巢原发性肿瘤具有诊断意义;但是ER/PR/Pax8阴性也不能排除原发性肿瘤 );
7、建议结合临床相关性影像学检查。有时候我们不能够做出明确的病理学诊断。这是可以接受的。
