Actuality of the topic
Benign ovarian tumors account for 75-80% of all ovarian tumors.
Benign ovarian tumors include concepts such as cysts and cysts of the ovaries.
Ovarian cysts are tumor-like formations characterized by fluid accumulation among
normal ovarian tissue surrounded by a clear capsule. These include: ovarian
follicular cyst, corpus luteum cyst, paraovarian cyst. Cystoma is a real tumor of the
ovary, which has all the characteristics of tumor growth (benign).

Content of the topic
Benign ovarian tumors account for 75-80% of all ovarian tumors.

Benign ovarian tumors include concepts such as cysts and cysts of the ovaries.
Ovarian cysts are tumor-like formations characterized by fluid accumulation among
normal ovarian tissue surrounded by a clear capsule. These include: ovarian
follicular cyst, corpus luteum cyst, paraovarian cyst. Cystoma is a real tumor of the
ovary, which has all the characteristics of tumor growth (benign).
In none of the organs is there such a histological variety of tumors as in the
ovary. According to the International Histological Classification compiled by WHO
experts (1973), ovarian tumors are divided into eight groups. Given its complexity
for perception not only by students but also by general practitioners, SK Serov
(1978) proposed a more simplified version of this classification.
I. EPITHELIAL TUMORS
A. Serous, mucinous, endometrioid, mesonephroid (clear cell), mixed;
and). benign - cystadenoma, adenofibroma, superficial papilloma;
b). borderline - intermediate forms of cystaden and adenofibrom;
in). malignant - adenocarcinoma, cystadenocarcinoma, papillary carcinoma.
B. Brenner's tumor.
a). benign;
b). border;
с). malignant.
II. TUMORS OF THE STROKE OF SEXUAL WEIGHT.
A. Granulosa-thecacellular tumors: granulosa-cellular, tecom-fibroma group,
non-classified tumors.
B. Androblastomas, tumors of Sertoli and Leydig cells (differentiated,
intermediate, poorly differentiated).
B. Ginandroblastoma.
G. Tumors that are not classified.
III. LIPID-CELL TUMORS.
IV. HERMINOGENIC TUMORS.
A. Dysgerminoma.
B. Tumor of the endodermal sinus.
B. Embryonic carcinoma.
R. Polyembrinoma.
D. Chorionepithelioma.
5
E. Teratomas (mature, immature).
J. Mixed germinogenic tumors.
V. GONADOBLASTOMA.
VI. SOFT TISSUE TUMORS (non-specific for ovaries).
VII. TUMORS THAT ARE NOT CLASSIFIED.
VIII. SECONDARY (METASTATIC) TUMORS.
IX. TUMOR-LIKE AND PRE-TUMOR PROCESSES: luteoma of
pregnancy, hypertecosis, follicular cysts, corpus luteum cyst, endometriosis,
inflammatory processes, paraovarian cysts.
3.3.1. Ovarian epithelial tumors consist of one or more types of stromal
epithelium in various combinations.
3.3.1.1. Serous epithelial cyst of the ovaries. Serous tumor cells produce
serous fluid or mucin. Serous tumors are single- or multichambered, large in size.
Their walls are dense, the contents are transparent, light, the inner surface of the
capsule is smooth.
At vaginal research the smooth-walled mobile formation of the rounded or
ovoid form laterally or behind from a uterus is defined.
Papillary serous cystadenomas, which are characterized by the presence of
papillary growths on the inner surface of the cyst capsule, are quite common. They
are often bilateral. The main complaints of patients with this pathology are: pain in
the lower abdomen, torsion of the leg of the tumor - acute, there are dysuric
disorders, increase in abdominal volume, infertility.
The diagnosis is established on the basis of the clinical course of the disease,
bimanual and ultrasound data.
3.3.1.2. Mucinous or pseudomucinous tumors. These are cysts whose
epithelial component is similar to the epithelium of the cervical canal. These are
multi-chambered rounded or oval-shaped tumor-like formations with an uneven
surface. They contain a viscous turbid liquid, often unilateral. The size varies from
small size to a giant tumor.
Clinically manifested by pain, locks, a feeling of heaviness in the lower
abdomen, dysuric disorders, abdominal enlargement. The most common complaint
is dull, numb, pain in the lower abdomen, sometimes paroxysmal, acute.
At vaginal research the thick-walled tumor of a rigid elastic consistence
laterally or behind a uterus is palpated, the tumor surface is uneven due to
multichamber. Rarely affected both ovaries, usually have a well-defined leg, and
therefore, there is a torsion.
Pseudomyxoma is a type of mucinous ovarian tumor.
6
3.3.1.3. Endometrioid tumors. Derived from the remnants of the Mullerian
epithelium. It is a single- or multi-chambered tumor containing a chocolate-colored
thick liquid. The inner surface of the capsule is covered with endometrioid
epithelium, which functions cyclically, like the epithelium of the uterine cavity.
More often it is a unilateral tumor, although there is a bilateral localization. The main
complaint is pain in the lower abdomen, mostly during or after menstruation.
3.3.1.4. Mesonephroid clear cell tumors are rare.
3.3.1.5. Brenner's tumor is a rare tumor that consists of epithelial components
located in the form of inclusions among the connective tissue of the ovaries. The
tumor has an oval or round shape, smooth outer surface and small size.
3.3.2. Tumors of the stroma of the genital tract. This is a group of hormoneproducing and hormone-dependent tumors. Hormonally active ovarian tumors are
tumors that originate from hormonally active structures of the "female" and "male"
part of the gonad, secreting respectively estrogen and androgens, causing
respectively the development of feminizing or virilizing symptoms. Their
occurrence is associated with the presence of embryonic residues and hormonal
imbalance in the body. Unlike all other ovarian tumors, hormone-producing tumors
are characterized by a clinically pronounced picture of the disease.
3.3.2.1. Granulocytic tumor. Sometimes mostly unilateral rarely reaches large
sizes. The source of its growth is granulosa follicles and cerebral cords. Clinical
manifestations are due to the hormonal activity of the tumor, which causes changes
in the appearance of the patient, due to the production of tumor cells by estrogenic
hormones. Girls have premature puberty, enlargement of the mammary glands, the
appearance of secondary sexual characteristics. In menopausal women,
menstruation resumes, often - metrorrhagia. In childbearing age, frequent bleeding,
sometimes amenorrhea, infertility, frequent miscarriages. Older patients look
younger than their years. Along with the signs of hyperestrogenism there is an
increase in skin turgor, swelling of the mammary glands. The ovaries may be slightly
enlarged.
3.3.2.2. Tecoma .. Develops from the cells of the inner shell of the follicle or
from the ovarian stroma. Its clinical manifestations are approximately the same as
in granulosa cell tumor and are due to increased estrogen production. At vaginal
research the slightly increased uterus and formation of an ovary of a dense
consistence, mobile, painless, unilateral is defined.
3.3.2.3. Fibroma .. Develops from the ovarian stroma - a unilateral tumor of
solid structure. It has a slow growth, dense consistency, may be asymptomatic. At
vaginal research the ovarian fibroma is located behind or on the side of a uterus.
Ultrasound helps in diagnosis.
3.3.2.4. Androblastoma. It develops from the elements of the male gonad. The
clinical course is dominated by signs of defeminization and masculinization of the
7
female body. The disease in most cases begins with amenorrhea, a gradual decline
in libido, male pattern hair growth, slow alopecia, flattening of the mammary glands,
coarsening of the voice. At inspection the tumor in the field of appendages of a
uterus, painless, elastic consistence, mobile, as a rule, unilateral is defined.
3.3.2.5. Ginandroblastoma. This is a combined tumor, in which on the one
hand there are structures characteristic of granulosa cell tumor, on the other - typical
tubules covered with cells such as sustenocytes. The clinic of this tumor may be
characterized by a small estrogenization.
3.3.3. Lipid cell tumors. These are rare tumors from the dystopian cortical
layer of the adrenal glands - hypernephroma, luteoma. Clinically manifested by
defeminization, masculinization, the presence of Cushing's syndrome, infertility,
anovulation, amenorrhea, hair growth on the upper lip and chin.
3.3.4. Germinogenic tumors. Arise from the elements of undifferentiated
gonads due to genetic disorders and malformations.
3.3.4.1. Dysgerminoma. This is the most common tumor. Some experts
attribute it to benign, but this tumor is fast growing and gives early lymphogenic
metastases. The tumor has no hormonal activity. The main symptom of the disease
is pain in the lower abdomen.
3.3.4.2. Endodermal sinus tumor and embryonic carcinomas. These are rare
tumors with a high degree of malignancy. They metastasize lymphogenically,
hematogenously and implantation.
3.3.4.3. Teratoma. Is a derivative of embryonic leaves. Sometimes cystic and
solid. Most mature ovarian teratomas are cystic, which include dermoid cysts. This
is a single-chamber formation with a smooth surface.
Immature teratoma is a malignant tumor.
Clinically manifested by abdominal pain. Menstrual function is not disturbed.
3.3.4.5. Gonadoblastoma. It is a homologue of different stages of development
of the gonad. The tumor is very rare, occurs in patients with gonadal dysgenesis.
Clinical manifestations - symptoms of verification. The tumor is often unilateral.
3.3.6. Tumors of soft tissues, non-specific for the ovaries. These tumors are
diagnosed according to the histological classification of soft tissue tumors.
3.3.7. Unclassified tumors. This group includes tumors that cannot be
classified as those types of tumors that are mentioned above.
3.3.8. Secondary (metastatic) tumors. They make up 20% of all ovarian
tumors, arise as a result of metastasis of malignant tumors of different localization
by lymphogenic, hematogenous and implantation-transperitoneal way.
3.3.9. Tumor-like formations of the ovaries.
8
These include ovarian cysts that occur as a result of fluid accumulation in the
anterior cavity, without epithelial lining. The result of these formations can be:
reverse development, transformation into a real tumor, twisting of the tumor leg.
3.3.9.1. The most common are follicular cysts of the ovaries. The
accumulation of fluid occurs due to its transudation from blood vessels, the follicular
epithelium does not participate in the accumulation of fluid. A follicular cyst is a
single-chamber, thin-walled cystic formation with light transparent contents.
Patients complain of lower abdominal pain, menstrual irregularities. The size of a
follicular cyst seldom exceeds 8-10 see
3.3.9.2. Cysts of the corpus luteum. The reason for their formation may be
inflammatory changes in the ovaries. In size, consistency, shape and clinical
manifestations, they are similar to follicular cysts.
3.3.9.3. Paraovarian cyst. It usually arises from the embryonic remnant of the
wolf's canal. Is a retention entity. The ovary does not participate in its formation. Its
capsule is thin-walled, the contents are transparent, the size is small. It develops
asymptomatically and, as a rule, is an accidental finding at professional examination.
The main methods of diagnosis of ovarian tumors: clinical methods (history,
complaints, rectovaginal examination); Ultrasound; CT; MRI; determination of
tumor markers (CA-125); examination of the gastrointestinal tract (fibrocolono-,
fibrogastroscopy); cytological method of examination of effusion in cavities, etc.
The main method of treatment of all real ovarian tumors is surgery. The scope
of the operation depends on: the type of tumor (pathomorphology), the woman's age,
the prevalence of the process (endometrioid ovarian tumors).
