说点与结果无关的话：里面有浆液性上皮样成分吗？大家的看法？

- 女 59 卵巢囊性肿瘤

1楼的图6，8-12和看上去比较worrisome。有expansile浸润的意思，特别是出现许多中性粒细胞 (?)，多提示恶性。2楼的图1, 5-7同样让人不放心，2楼图2，3看上去像微浸润，图4左侧视野为典型的交界瘤改变，如果这些区域占整个肿瘤的大部分，个人意见：考虑为交界瘤，局部恶性变。
同意Dr. cqzhao的观点：“Difficult to evaluate these kinds of cases based on photos”。

mucinous cystadenoma of borderline malinancy.
Agree with Dr. Zhao that the photos shown here don't show enought cytoatypia for intraepithelial carcinoma.
The small glands in stroma: i don't favor invasion. Expansile invasion may be present, but not sure.
For mucinous tumor of ovary, you need to submit all the tissue for microscopic evaluation.
Difficult to evaluate these kinds of cases based on photos.
Agree above interpretations.
1. M-LMP, sure.
2. M-LMP with focal intraepithelial carcinoma. It means that focal marked cytologic atypia (nuclear grade 3). It is not obvious in this case.
3. The main issue is if foci of microinvasion or invasion is present.
The patterns of invasion for ovarian mucinous tumors include stromal breakdown invasion and cofluent/expansile type. The latter is much more common than true stromal breaddown.
The criteria: for confluent type invasion: focal conflent growth >3 mm, and some ones use the size >5 mm.
4. Louzhu must read slides carefully to evalute if stromal invasion or confluent type of invasion is present. worred above photos.
5. We routinely do the stains for CK7, CK20, CDX2 for all ovarian mucinous tumors to rule out the possibility of metastatic tumor.
