Benin Tumors of the Uterus and the Ovary Benign tumors of women’s reproductive system PLAN OF LECTURE 1. Benign tumors of the uterus • Etiopathogenesis • Classification • Clinical symptoms • Diagnostics • Management 2. Benign ovarian tumors • Etiopathogenesis • Classification • Clinical symptoms • Diagnostics • Management Leiomyoma smooth muscule + fibrous connective tissue Frequency of uterine myoma makes 15-25% among women after 35-40 years Etiopathogenesis myoma - mesenchymal tumor (region of active growth formation around the vessels growing of tumor) + hyperoestrogenism Myomas are rarely found before puberty, and after menopause. The association of fibroids in women with hyperoestrogenism is evidenced by endometrial hyperplasia, abnormal uterine bleeding and endometrial carcinoma. Myomas increase in size: during pregnancy, with oral contraceptives, after delivery. Accoding to Location of uterus myomas Hysteromyoma classification: • А. By the node localization: 1. subserous – growth in the direction of the perimetrium; 2. intramural (interstitial) – growth into the thickness of the uterine wall; 3. submucous – node growth into the uterine cavity; 4. atypical – retrocervical, retroperitoneal, antecervical, subperitoneal, perecervical, intraligamentous. • В. By the node size (small, medium, and large) • C. By the growth form • (false – conditioned by blood supply disturbance and edema, and true – caused by the processes of smooth muscle cells proliferation). • D. By the speeding of the growth (fast and slowly) The symptoms of uterine fibroids Fibroids can also cause a number of symptoms depending on their size, location within the uterus, and how close they are to adjacent pelvic organs. • Pelvic pain • Abnormal uterine bleeding • Pressure on the bladder with frequent or even obstructed urination, and pressure on the rectum with pain during defecation • Pelvic ultrasonography • Submucosal tumor Hysterosalpingography (Submucosal tumor) Hysteroscopy (Submucous macronodular fibroid) Laparoscopy Interstitial-Submucosal myoma Hysteromyoma complications • “birth”, • necrosis, • myomatous node suppuration, • node pedicle torsion, • rupture of the node capsule and vessels, • malignant change of the fibromyoma. • Infertility Pedunculated leiomyoma “Birth”-node Necrosis node Uterine Fibroid Embolization (UFE) or Uterine Artery Embolization (UAE) - a nonsurgical procedure that blocks blood flow to fibroids in the uterus. Embolization is done with local anesthesia, and there are no incisions or cuts in the skin. A thin flexible tube is threaded into the blood vessels that supply blood to the fibroid; a solution is then injected into the blood vessels. This blocks the blood supply to the fibroid, causing it to shrink. Fibroids treated with embolization shrink by half or more. Normal uterine tissue usually remains unharmed, because it is supplied by other arteries. Women who are considered the best candidates for embolization are women who: • Have fibroids that are causing heavy bleeding • Have fibroids that are causing pain or pressing on the bladder or rectum • Don't want to have a hysterectomy • Don't want to have children in the future Complications of embolization are not common, but can occur. They are: • Infection - the most serious, potentially life- threatening complication of embolization. See your doctor immediately if you have a high fever and feel ill or notice pus in your vaginal discharge. In rare cases, emergency hysterectomy is needed to treat an infected uterus. • Loss of menstrual periods • Premature menopause • Scar tissue formation Myolysis Myolysis is the destruction of muscle tissue. Myolysis is generally recommended for smaller fibroids. It is not recommended for women who hope to have children. These treatments can cause serious pregnancy complications, such as uterine scarring and infection; these can be dangerous to both mother and fetus. • Laser (myolysis) - usually done by laparoscopy. A laser is used to remove the fibroid or clot the blood supply to the fibroid, causing the fibroid to shrink and eventually die. • Cold (cryomyolysis) - usually done by laparoscopy. Liquid nitrogen is used to freeze the fibroid. • Electric current - Myoma coagulation (myolysis) - usually done by laparoscopy. An electrical needle is passed directly into the fibroid delivering high-temperature energy to destroy both the fibroid and the blood vessels feeding it. • High-frequency focused ultrasound - Using a high-intensity ultrasound beam, the Magnetic Resonance Imaging (MRI) scanner helps the doctor locate the fibroid, and the ultrasound sends out very hot sound waves to destroy it. tumor of a woman’s uterus (womb). uterine fibroids A submucous myoma Interstitial fibroid uterus.

It is the most common type of ovarian tumor. • Stromal tumors – these benign and malignant tumors begin in the part of the ovary that manufactures female reproductive hormones. It is very rare and when cancerous is considered a low-grade cancer. • Germ cell tumors – these tumors begin in the cells that develop into eggs. The majority of germ cell tumors are benign, but sometimes can develop into cancer. These are most common in younger women and, if treated early, fertility can be preserved.

Clinical norma Ovariorum (norma) Follicles dominant Functional cysts form from the fluid-filled cavities (follicles) in the ovaries. Functional follicle cyst Functional luteal cyst with septa Endometriod tumors Cyctadenoma Cyctadenoma Mucinous cystoma / thecoma Benign cyctic teratoma (dermoid cyct) Benign cystic teratomas (dermoid cysts): These tumors usually develop from all three layers of tissue in the embryo (called germ cell layers). All organs form from these tissues. Thus, teratomas may contain tissues from structures, such as nerves, glands and skin. Cystadenocarcinoma Ovarian Cyst - Symptoms • sharp pains in the lower abdomen; • severity in the hip; • heavy bleeding during menstruation, irregular menstruation; • weakness, nausea, sometimes vomiting after sexual intercourse or intense physical education; • pressure in the abdomen during urination; • constant body temperature above 38 ° C; • sudden weight loss with normal nutrition. •It begins to put pressure on neighboring organs Anatomical and surgical pedicle The pedicle of an ovarian cyst showing the relations of the ovarian vessels, the ovarian ligament and the fallopian tube, together with the anastomosing branch of the uterine artery. Investigations • Ultrasound. Transabdominal transducer is employed if the tumour is abdominal. Otherwise transvaginal ultrasound (TVS) gives more detailed features of the tumour. » Radiograph of abdomen/pelvis which may demonstrate a soft tissue shadow, or teeth in a dermoid (molar tooth). » Diagnostic laparoscopic examination may be needed in a few cases. » Intravenous pyelography will exclude a hydronephrosis. Ultrasound can also diagnose it. » In all suspected metastatic ovarian cancers, a barium meal should be performed to exclude gastrointestinal primary carcinoma. » Radiograph of chest will rule out pulmonary metastasis and also hydrothorax in case of Meigs syndrome. » Breast examination will rule out pregnancy as well as detect a metastatic growth. Tissue markers : CA-125, NB/70k, HE4 Treatment Cystectomy Key Points 1 The tumours are often asymptomatic to begin with, and are often far advanced by the time they are diagnosed. 2 Sex cord tumours have a potential to secrete hormones which may manifest clinical symptoms like precocious puberty, menstrual disturbances and postmenopausal bleeding. Virilizing effects may be observed in masculinizing tumours. 3 Bilateral tumours, rapidly growing tumours and presence of ascites are suggestive of malignancy and require investigations. 4 Tumour markers like CA-125, HE 4 are particularly useful in postmenopausal women suspected of having a malignant epithelial cell tumour. 5 Benign ovarian tumour is surgically dealt with by ovarian cystectomy, ovariotomy, laparoscopic dissection of the cyst in a young woman and hysterectomy ith bil t l l f d i ld .

    ISSN: 0975-8585 Research Journal of Pharmaceutical, Biological and Chemical Sciences Pregnancy Luteoma Along With Benign Cystic Teratoma: A Case Report. Vijay Kumar Bodal1*, Manjit Singh Bal1, Sarbhjit Kaur2, Manjit Kaur Mohi2, Anudeep Gill1, and Mohanvir Kaur1. 1Department of Pathology, Government Medical College, Patiala, Punjab, India. 2Department of Obstetrics and Gynecology, Government Medical College, Patiala, Punjab, India. ABSTRACT It is a rare to find simultaneous benign cystic teratoma and pregnancy luteoma in an ovary. Mature cystic teratoma is the most common type of ovarian germ cell neoplasm. About 0.8% to 12.8% of reported cases of mature cystic teratorma have occurred during pregnancy. Pregnancy luteoma is a distinctive, non- neoplastic lesion of pregnancy, characterized by solid proliferation of luteinized cells, and tumour-like ovarian enlargement that regresses during puerperium. To date fewer than 200 cases of pregnancy luteoma have been reported. We presented a rare case of a multiparous 26 year old gravid female who presented with mass and moderate pain in abdomen. Keywords: pregnancy, luteoma, teratoma, benign cyst. *Corresponding author March - April 2014 RJPBCS 5(2) Page No. 1593 ISSN: 0975-8585 CASE HISTORY A 26 years old female, gravida 3 para 2, presented with amenorrhea since 3 months and palpabel mass with moderate pain in the abdomen for 2 months. Clinical and radiological diagnosis of dermoid cyst ovary was made and intrauterine pregnancy was confirmed on ultrasound. Laparotomy was done and ovarian mass was removed which was subjected to histopathological examination. RESULTS On gross examination the mass was in the form of globular gray-white, gray-brown soft tissue measuring 7×5×4 cm in size.

  • Progesterone-Responsive Vaginal Leiomyoma and Hyperprogesteronemia Due to Ovarian Luteoma in an Older Bitch L
    Ferré-Dolcet et al. BMC Veterinary Research (2020) 16:284 https://doi.org/10.1186/s12917-020-02507-z CASE REPORT Open Access Progesterone-responsive vaginal leiomyoma and hyperprogesteronemia due to ovarian luteoma in an older bitch L. Ferré-Dolcet* , S. Romagnoli, T. Banzato, L. Cavicchioli, R. Di Maggio, A. Cattai, M. Berlanda, M. Schrank and A. Mollo Abstract Background: This is the first report about a vaginal leiomyoma concomitant with an ovarian luteoma in a bitch. Case presentation: A 11-year-old intact female Labrador retriever was referred because of anuria, constipation and protrusion of a vaginal mass through the vulvar commissure. The bitch had high serum progesterone concentration (4.94 ng/ml). Because of the possibility of progesterone responsiveness causing further increase of the vaginal mass and since the bitch was a poor surgical candidate a 10 mg/kg aglepristone treatment was started SC on referral day 1. A computerized tomography showed a 12.7 × 6.5 × 8.3 cm mass causing urethral and rectal compression, ureteral dilation and hydronephrosis. A vaginal leiomyoma was diagnosed on histology. As serum progesterone concentration kept increasing despite aglepristone treatment, a 0.02 ng/mL twice daily IM alfaprostol treatment was started on day 18. As neither treatment showed remission of clinical signs or luteolysis, ovariohysterectomy was performed on referral day 35. Multiple corpora lutea were found on both ovaries. On histology a luteoma was diagnosed on the left ovary. P4 levels were undetectable 7 days after surgery. Recovery was uneventful and 12 weeks after surgery tomography showed a reduction of 86.7% of the vaginal mass.

These diseases are diagnosed invasively, which entails delayed treatment and a worse clinical outcome. New options for diagnosis and prognosis are needed. PubMed, OVID, and Scopus were searched for research papers on metabolomics in physiological fluids and tissues from patients with uterine diseases. The search identified 484 records. Based on inclusion and exclusion criteria, 44 studies were included into the review. Relevant data were extracted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) checklist and quality was assessed using the QUADOMICS tool. The selected metabolomics studies analysed plasma, serum, urine, peritoneal, endometrial, and cervico-vaginal fluid, ectopic/eutopic endometrium, and cervical tissue.

  • Ovarian Tumors
    Ovarian Tumors 803-808-7387 www.gracepets.com These notes are provided to help you understand the diagnosis or possible diagnosis of cancer in your pet. For general information on cancer in pets ask for our handout “What is Cancer”. Your veterinarian may suggest certain tests to help confirm or eliminate diagnosis, and to help assess treatment options and likely outcomes. Because individual situations and responses vary, and because cancers often behave unpredictably, science can only give us a guide. However, information and understanding for tumors in animals is improving all the time. We understand that this can be a very worrying time. We apologize for the need to use some technical language. If you have any questions please do not hesitate to ask us. What are the ovarian tumors? The ovary contains several different cell types. These include the germ cells, which make the eggs, the supporting (stromal) and hormone-producing cells as well as epithelium, connective tissue and blood vessels. Any or all of these cell types may become cancerous. When germ cells become cancerous, the tumors are called dysgerminomas. Tumors of ovarian stromal cells include granulosa cell tumors, thecomas and interstitial cell tumors (luteomas). These tumour types overlap and they may occur singly or in any combination. Epithelial tumors include papillary adenoma and adenocarcinomas. Rare types of ovarian tumour include the teratoma formed by embryonic germ (primitive) cells that develop abnormally to produce many different tissues. Some ovarian cancers are benign and others malignant. In some cases, removal of the affected ovary will be curative. Spread to other internal organs (metastasis) is possible with some types, particularly Reproductive Anatomy the larger tumors.

  • Association Between Ovarian Tumors and Uterine Endometrial Lesions in Rats*
    J Toxicol Pathol 5: 215•`222, 1992 ASSOCIATION BETWEEN OVARIAN TUMORS AND UTERINE ENDOMETRIAL LESIONS IN RATS* Hiroshi Onodera, Yuko Matsushima, and Kunitoshi Mitsumori Division of Pathology, Biological Safety Research Center, National Institute of Health Sciences Takaharu Nagaoka Research Laboratories, Yoshitomi Pharmaceutical Industries Ltd. Tsuyoshi Kitamura, Jin Lu, and Akihiko Maekawa Department of Pathology, Sasaki Institute Abstract: Granulosa cell tumors/luteomas of the ovary were induced at very high incidence in the offspring of F344 rats receiving N-nitrosobis (2-oxopropyl)amine (BOP) transplacentally (Jpn. J. Cancer Res., 81: 1077-1080, 1990). In addition to ovarian tumors, atrophic and hyperplastic lesions were also frequently observed in the ovary and uterus of BOP-treated animals, respectively. In order to investigate the relation between granulosa cell tumors and uterine endometrial lesions, the lesions in BOP-treated rats with ovarian tumors were compared to those in the rats without tumors. While no endometrial adenocarcinoma was found in both rat groups, the incidence and degree of atypical, and adenomatous endometrial hyperplasias were slightly high in rats with ovarian tumors, as compared to rats without tumors, while being not significant. In the assay of plasma gonad steroids, hormonal imbalance was clearly detected in BOP-treated animals and the 17ƒÀ-estradiol: progesterone (E2: P) ratio was higher in BOP-treated rats with ovarian tumors than control rats or treated rats without tumors. These results suggest that a slight association between ovarian tumors and endometrial proliferative lesions exists in rats and hormonal imbalance, particularly an increased E2: P ratio, might play an important role in the association.

A white, lobular mass was found in the right ovary of a pregnant Risso’s dolphin (Grampus griseus) at necropsy. The mass was unilateral and occupied most of the pre-existing ovarian tissue. Histologically, the mass was composed of diffuse sheets of polyhedral cells with J. Vet. Med. Sci. abundant eosinophilic cytoplasm and oval nuclei, separated by fibrous connective tissue. Only 79(10): 1749–1752, 2017 a few ovarian follicles were observed at the periphery of the mass. Immunohistochemically, the large eosinophilic cells were positive for vimentin and negative for pan-cytokeratins.
