INVASIVE IMPLANT/LOW-GRADE SEROUS CARCINOMA Figure 4-20 INVASIVE IMPLANT/LOW-GRADE SEROUS CARCINOMA A–C: The presence of invasion is now synonymous with low-grade serous carcinoma. In the case of an invasive implant, the invasion is identified in the peritoneal or omental tumor, and is not found ...

LOW-GRADE SEROUS CARCINOMA Figure 4-25 LOW-GRADE SEROUS CARCINOMA There is an abundance of epithelium compared to stroma. In addition, there are no papillae with hierarchical branching, but rather abundant invasive epithelial structures in a stroma with retraction.

SEROUS PSAMMOCARCINOMA Figure 4-27 SEROUS PSAMMOCARCINOMA This low-grade serous carcinoma has abundant psammomatous calcifications. By definition, more than 75 percent of the tumor nests must contain calcifications to diagnose serous psammocarcinoma.
