Study Notes
Ovarian Disorders
- Inflammation of the Ovary (Oophoritis): Oophoritis is inflammation of one or both ovaries, often preceded by infection of fallopian tubes or the peritoneum. It's part of chronic pelvic inflammatory disease (PID), an infection and inflammation in the upper female genital tract (uterus, fallopian tubes, and ovaries). Women under 35 are most at risk for PID and oophoritis. It rarely develops before menstruation, during pregnancy, or after menopause. Extensive scarring (fibrosis) can result in infertility.
Non-Neoplastic Ovarian Cysts
-
Follicular Cysts: These ovarian cysts are common, originating from unruptured ovarian follicles. Often multiple, they range in size, typically around 1.5 cm, but can be quite large (over 10 cm). The lining of the cyst resembles a normal follicle (granulosa and theca cells), but they rarely produce estrogen.
-
Luteal Cysts: These are cysts of the corpus luteum, typically around two centimeters in diameter, but can sometimes be larger (up to three cm). Usually multiple, lined by luteal cells, they primarily secrete progesterone.
-
Chocolate Cysts (Endometriotic Cysts): These cysts develop due to the growth of endometrial tissue outside the uterus.
-
Germinal Inclusion Cysts: These cysts form when the germinal epithelium invades the ovarian stroma.
Polycystic Ovary Syndrome (PCOS)
- PCOS is common, affecting 12-21% of reproductive-aged women. Up to 70% of people with PCOS go undiagnosed, and it is more common in obese women. It can lead to infertility. Two of the three criteria below are required for diagnosis:
- Oligomenorrhea/anovulation
- Hyperandrogenism (hirsutism or elevated free androgen index/free testosterone)
- Polycystic ovaries on ultrasound
Classification of Ovarian Tumors
-
Surface Epithelial Tumors: Includes:
- Serous tumors (60% benign, 25% malignant, 15% borderline)
- Mucinous tumors (80% benign, 5-10% malignant, borderline)
- Brenner tumor
- Endometrioid tumors (20% of all ovarian cancers, often associated with endometriosis)
- Clear cell tumors
-
Germ Cell Tumors: Includes:
- Teratomas (mostly cystic, dermoid cysts)
- Dysgerminoma
- Embryonal carcinoma
- Yolk sac tumor
- Other germ cell tumors
-
Sex-cord Stromal Tumors: Includes:
- Granulosa-theca cell tumor (common in postmenopausal women)
- Sertoli-Leydig cell tumor
- Gynandroblastoma
-
Soft Tissue Tumors: Includes:
- Fibroma
- Angioma
-
Metastatic Secondary Tumors: Cancer spreading to the ovaries from other parts of the body, frequently from the gastrointestinal tract (GIT) or breast. Krukenberg tumor is a type of metastatic ovarian cancer (usually from the stomach) that appears bilaterally.
Detailed information on Serous Cystadenomas
-
Grossly: They are rounded masses (large or small), usually unilateral, with a smooth thin wall. They're often unilocular, containing clear yellowish fluid, though papillary growths may project inside or outside the surface.
-
Microscopically: The lining of the cysts is tall columnar ciliated cells. Small microscopic papillae are present.
Detailed information about Papillary Serous Cystadenocarcinoma
-
Grossly: Featuring solid papillary projections that penetrate the cyst capsule (on both sides of the cyst wall). Solid loculi are sometimes seen.
-
Microscopically: The lining epithelium consists of multiple layers and demonstrates features of malignancy. Psammoma bodies may be present.
Information on Borderline Serous Tumors
-
Grossly: Borderline serous tumors often resemble benign serous tumors.
-
Microscopically: These tumors show characteristics of malignant serous tumors without the invasion of the supporting tissue (stroma).
Mucinous Tumors
- Benign (Mucinous Cystadenoma): Approximately 80% of mucinous tumors are benign.
- Malignant (Mucinous Cystadenocarcinoma): Roughly 5-10% of mucinous tumors are malignant.
- Borderline: A less aggressive tumor form midway in characteristics between benign and malignant.
Mucinous Cystadenoma
-
Grossly: It can be large and ovoid or lobed; typically unilateral; multilocular, filled with a gelatinous material. The cyst wall is thick and fibrous.
-
Microscopically: Lined by tall columnar cells, showcasing apical mucinous vacuolation.
Mucinous Cystadenocarcinoma
- Capsule Invasion: A key feature is the atypical cells and invasion of the cyst capsule. Solid masses within the tumor are often present.
Borderline Forms (of Mucinous Tumors):
- Similar to malignant forms; however, there is no capsule invasion.
Complications of Benign Serous and Mucinous Cystadenomas
- Pedicle Torsion: Rotation of the cyst leading to bleeding.
- Rupture: The cyst might burst, potentially causing acute abdominal pain and other related symptoms.
- Pressure Effects: The cyst's presence can exert pressure on adjacent organs and structures.
- Malignant Change: Rarely, benign cystadenomas can transition to cancerous forms.
Endometrioid Tumors
- Incidence: Comprise about 20% of ovarian cancers.
- Endometriosis: Often linked to ovarian endometriosis (presence of endometrial tissue outside the uterus).
- Gross Morphology: Often have solid and cystic areas.
- Bilaterality: Approximately 40% are bilateral.
- Microscopic Appearance: The glandular structures resemble endometrial adenocarcinoma.
Brenner Tumors
- Benign Predominance: Mostly benign, unilateral tumors. Cystic form is less prevalent.
- Sizes: Encompass a wide size range, from small lesions to substantial masses.
- Composition: Composed of dense fibrous stroma and nests of transitional cells.
Germ Cell Tumors (Teratomas)
-
Origin: Arise from totipotent cells, capable of differentiation into three germ cell layers.
-
Mature Teratomas (Dermoid Cysts): Mostly cystic, small, often referred to as dermoid cysts. They are lined with skin, have adnexal structures, and frequently contain hair, often with sebaceous secretions.
-
Microscopic Details: Include epidermis, hair follicles, sebaceous glands, dental structures (teeth), cartilage, bone, thyroid tissue, and other tissues from the various germ layers.
-
Malignant Potential: Malignant change (squamous cell carcinoma) can occur in 1% of teratoma cases.
-
Monodermal Teratomas: Comprise struma ovarii (thyroid tissue), carcinoid, and combined forms; struma ovarii is the most common monodermal teratoma type.
-
Immature Teratomas: More prevalent in adolescents and young women (mean age 18 years). Bulkiness and a solid structure with areas of tissue breakdown (necrosis) and bleeding (hemorrhage) are significant features of this type. Microscopic examination reveals a mixture of immature tissues with potential for differentiation into various tissues, including cartilage, glands, bone, muscle, and nerve tissue.
Dysgerminoma
- Origin: Ovarian counterpart of seminomas.
- Patient Group: Common among children, adolescents, and young women.
- Gross Characteristics: Generally, it appears as a solid, unilateral mass; fleshy and ranges in color from yellowish-white to gray-pink.
- Microscopic Features: Large cells with clear cytoplasm forming sheets or cords. Scant fibrous stroma is usually present alongside dispersed lymphocytes.
Sex Cord Stromal Tumors
- Origin: They develop from the sex cords of embryonic gonads or the ovarian stroma.
- Functional Characteristics: Often secrete hormones, such as estrogen (granulosa and theca cell tumors) or androgen (Sertoli-Leydig cell tumors).
Granulosa-Theca Cell Tumor
-
Occurrence: Frequent in postmenopausal women.
-
Gross Features: Commonly unilateral, featuring solid and cystic regions, and is often encapsulated. It comes in a varying spectrum of sizes.
-
Potential Malignancy: Potentially malignant (5-25%).
-
Microscopic Details: Consisting of a mix of granulosa and theca cells. Granulosa cells are small, cuboidal, arranged in clumps, cords, or sheets, often forming rosettes. Theca cells are spindle-shaped and are associated with lipid droplets in their cytoplasm.
Fibroma-Thecoma
- Composition: Primarily well-differentiated fibroblasts.
- Unilateral Nature: Usually unilateral, solid, and firm masses.
- Associated Conditions: Approximately 40% are linked to hydrothorax and ascites (Meigs syndrome).
Metastatic Tumors
- Common Sources: Primarily from breast and gastrointestinal tract tumors.
- Krukenberg Tumor: A specific example, often originating from the stomach, showing bilateral spread through the peritoneal cavity.
