| 姓 名： | ××× | 性别： | 女 | 年龄： | 39 |
| 标本名称： | 卵巢囊性肿物 | ||||
| 简要病史： | 肺癌术后2个多月，阴道不规则流血10余天，下腹痛3天， | ||||
| 肉眼检查： | 大体：肿物大小14x10x7cm，表面光滑，切面多囊如蜂窝样，囊内充满血液。整个切面均为红褐色，仅少许部分灰白色。 | ||||
术中所见：左侧卵巢囊性增大，18x16x15cm，色紫褐色，蒂部扭转一周，
镜下出血严重，中央区组织大多出血、坏死，许多上皮细胞脱落与红细胞混在一起，边缘可见多囊，上皮未脱落。细胞有异型性，但分裂相难找。

Difficult case based on photos only. CCC should be considered. But cytomorphology is more like serous borderline tumor with focal stromal invasion. Depending on the areas of invasion, we can call low grade serous carcinoma or serous border line tumor with microinvasion.
The prognosis and treatment of ccc and serous border line tumor with microinvasion (or low grade serous ca) are different. So the pathology dx is very important. louzhu must be sure your dx before you release the case.
Another point is that ovarian serous ca includes high grade and low grade types. Most of the ovarian serous carcinoma are high grade type. Rare are low grade type. Serous borderline tumor can be progress to carcinoma--low grade serous ca.
This is real difficult case. Tumor grows in the cystic surface with micropapillary structure. The cells are relative uniform and hobnail-like appearance with round nuclei. The detached clusters of cells in the last photos show occasional clear cytoplasm. Photos 7-8 show stromal invasion of small tumor nests. The cytomorphologic feture are not like classic serous borderline or low grade seroud ca or classic ccc. The papilla in ccc generally show hyalinazed core, which is not present in this case.
Considering all morphologic features and grwoth pattern, I favor a dx of clear cell ca for this case. I cahnge my interpretation.
Anyway it is not an easy case. It will be much easier to read all sections of true glass slides.
Just for your reference.
