• thyroid gland tissue in ovary

  Etiology
  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

  low 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

  PO
  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 (...)
