thyroid gland tissue in ovary
29 April 2020Etiology
struma ovarii / ovarian mature teratoma Struma ovarii represents less than 3% of ovarian teratomas. It can be associated with thyroid biology abnormalities, and in exceptionally rare cases it can be malignant.

ovarian serous borderline tumor, micropapillary variant
11 February 2020low grade serous carcinoma PO
Definition : micropapillary variant ovarian serous borderline tumor.
Ovarian serous borderline tumor, micropapillary variant behaves like low-grade adenocarcinoma. It appears to be derived from serous borderline tumor or adenofibroma. Invasive if destructive infiltrative growth; most are non-invasive.
It recurs as classic serous carcinoma.
Prognosis : 10 year survival is 70% vs. 100% for borderline tumors

ovarian serous borderline tumor with microinvasion
11 February 2020PO
Definition : Microinvasion within borderine tumors is defined by small stromal foci of single cells / small clusters of cells, occasionally cribriform or rounded aggregates of papillae with eosinophilic cytoplasm and minimal / absent stromal reaction.
The invasive epithelium may be up to 10 mm2 or 3 mm in greatest dimension (Mod Pathol 1988;1:407).
There may be diffusely scattered invasive foci without discrete aggregates - must sample well (Hum Pathol 1996;27:521, Hum Pathol (...) -
