Epithelial Ovarian Tumors Digital Slide Review: Key Takeaways
0:52 Serous Cystadenoma: Features include club-shaped papillary formations, cilia (indicating serous type), and corpora albicans (evidence of past ovulation) in adjacent normal ovary.
2:18 Serous Borderline Tumor: Exhibits hierarchical branching (characteristic of borderline architecture), detached eosinophilic cells, and some areas with invasive implants.
4:12 Micropapillary Serous Carcinoma: Displays "head of Medusa" or "caput medusae" pattern (direct transition from large club shapes to narrow projections), indicating micropapillary architecture. More extensive sampling is recommended due to higher risk of advanced stage.
5:59 High-Grade Serous Carcinoma in Fibroadipose Tissue: Shows high mitotic activity, pleomorphism (cells with varying appearances), atypical mitoses, macronucleoli, and a nested architecture within fibroadipose tissue, all suggestive of high-grade malignancy.
7:14 High-Grade Serous Carcinoma in Ovary: Presence of necrosis, apoptotic cells, macronucleoli, and pleomorphism, indicating high-grade serous carcinoma within the ovary.
8:03 Mucinous Cystadenoma: Demonstrates intracytoplasmic mucin, no significant proliferation or stratification, and simple glandular architecture, characteristic of a benign mucinous cystadenoma.
9:45 Mucinous Borderline Tumor: Presents with increased proliferation compared to a cystadenoma, surface papillary projections, and a focus on evaluating gland-to-stroma ratio to distinguish from borderline features.
11:33 Mucinous Carcinoma: Shows areas of necrosis, invasive/destructive growth pattern, and significant nuclear atypia, suggestive of a mucinous carcinoma.
12:25 Endometrial Adenofibroma: Reveals widely spaced endometrial-type glands, no significant atypia, and a benign appearance.
13:47 Endometrial Adenocarcinoma: Features complex glandular branching, cribriform (perforated) pattern, apoptosis, mitotic activity, and increased nuclear pleomorphism compared to adenofibroma, indicating malignancy.
14:53 Clear Cell Carcinoma: Displays complex architecture, characteristic clear cytoplasm (though not always present), hobnail-shaped cells, and sometimes hyaline (glassy) cores.
16:31 Brenner Tumor: Characterized by firm consistency, transitional type epithelial nests in hyaline stroma, and potential for mucinous metaplasia or cysts.
17:54 Borderline Brenner Tumor: Shows more complex transitional epithelium lining cysts and potentially infiltrative growth, but not necessarily malignant.
19:01 Seromucinous Borderline Tumor: Combines features of both serous (cilia) and mucinous (intracytoplasmic mucin) tumors, often associated with endometriosis. It displays hierarchical branching and eosinophilic cells similar to serous borderline tumors.
