Flashcard 6: Ovarian tumor associated with a pulling sensation in the groin and histology showing bundles of spindle-shaped fibroblasts?
Answer: Ovarian Fibroma
Extra: • Clinical: Pulling sensation in groin.
• Histology: Bundles of spindle-shaped fibroblasts.
• Association: Meigs syndrome (Ovarian fibroma, Ascites, Hydrothorax).
Flashcard 7: What is the characteristic histological finding and cell type in a Brenner tumor?
Answer: "Coffee bean" nuclei; contains Walthard cell rests (transitional epithelium)
Extra: Brenner tumor:
- Mostly benign ovarian surface epithelial tumor.
- Histology: Characterized by "coffee bean" nuclei (longitudinal nuclear grooves) and nests of transitional epithelium (resembling bladder mucosa) called Walthard cell rests.
- Gross: Solid, tan-white/yellow, well-encapsulated.
Flashcard 8: Is mucinous cystadenocarcinoma benign or malignant?
Answer: Malignant
Extra: Mucinous cystadenocarcinoma is the malignant counterpart of mucinous cystadenoma. It is a common primary surface epithelial tumor of the ovary, characterized by multiloculated cysts lined by atypically proliferated mucinous epithelium showing stromal invasion.
Flashcard 9: Morphological features of Mucinous Cystadenoma?
Answer: Multilocular cyst lined by mucus-secreting epithelium (Benign)
Extra: Mucinous cystadenomas are most commonly found in the ovary or pancreas. Characterized by large, multiloculated cysts filled with gelatinous fluid. Unlike serous cystadenomas, these are less likely to be bilateral in the ovary.
Flashcard 10: teratoma
Answer:
Extra: cystic growths fillled with fat, teeth, hair, bone, cartilagemature (dermoid cyst) - usually benign
