[Sertoli-Leydig cell tumor of the ovary].

Sertoli-Leidig cell tumor of the ovary is a rare tumor. It accounts for 0.5 - 1% of all ovarian tumors. Sertoli-Leidig cell tumors are commonly benign and they occur in young women who desire further childrearing. Although, the treatment must be as conservative as possible. For the malign Sertoli-Leidig cell tumor, radical treatment is required. The aim of this work is the analysis of clinical, para-clinical and therapeutic aspects of these tumors.

[Giant placental chorioangioma].

The large placental chorioangioma is a non-trophoblastic vascular tumor of placenta which size is more than 4 cm. It's a rare tumor, the incidence is between 1/3500 and 1/9000 birth. We analyze, on base of our case and from a literature review, the ultrasonography aspects of this tumor: we bring out also the physiological mechanisms of maternal and fetal complications and finally we detail the therapeutic possibilities. Chorioangioma appears in ultrasound scan like a thoroughly limited hypo-echogenic zone The vascular origin of the tumor can be confirmed by color Doppler. A left-right shunt effect results from arterio-venous communications and causes backwardness growth and fetal death in-utero The fetus is exposed to anemia and microangiopathic thrombopenia The maternal complications are: hydramnios, abruption placenta, premature ruptured membrane. Therapeutic possibilities are reduced: In several fetal anemia, blood transfusion can be done. Some techniques for tumor devascularization are be tried by someone.

[Association fibromyoma and pregnancy. About 23 cases].

UNLABELLED: The coexistence of leiomyoma and pregnancy may lead to complications with unequal gravity. MATERIAL AND METHODS: The authors propose a retrospective study about 23 cases of association of fibromyoma and pregnancy collected over a period of seven years. OBJECTIVES: Study of the effect of fibromyoma on pregnancy and vice-versa. Analysis mode of delivery. RESULTS: Aseptic necrobiosis: 21.7%. Urinary tract compression: 4.3%. Miscarriage: 13%. Threatened premature birth: 26%. Caesarean section: 47.8%. Premature birth: 8.6 %. Neonatal death: nil. CONCLUSION: Maternal morbidity due to this association is important. It is essential that pregnant women be aware of the importance of prenatal consultation during the first trimester of pregnancy.

[Postmenopausal uterine bleeding. Analytic study about 65 cases].

UNLABELLED: Postmenopausal uterine bleeding is frequent in gynecology. This symptom can reveal benign causes as well as cancers. So it's essential to rule out organic pathology. MATERIALS AND METHODS: We propose a retrospective study of 65 postmenopausal women who had uterine bleeding for two years. OBJECTIVES: - To study the relative frequency of different causes of postmenopausal uterine bleeding. - To evaluate the different investigation procedures. RESULTS: In 65 cases of postmenopausal bleeding, we found: - 6 cases of cancer (9.2 %): 4 cases of cancer of uterine corpus and 2 cases of cancer of uterine cervix. - Benign pathology was more frequent (59 cases : 90.8%), essentially represented by endometrial atrophy (37 cases) and hyperplasia (11 cases). - Hysteroscopic aspect in the 4 cases of endometrial cancer: - Polypoid hypertrophy: 2 cases. - Simple hyperplasia: 2 cases. CONCLUSION: Despite the fact that benign pathology is more frequent than malignancy as a cause postmenopausal uterine bleeding, we must always rule out a cancer by oriented biopsy.

[Breech presentation: vaginal delivery or planned caesarean section?].

UNLABELLED: Breech delivery is a high risk situation because of its numerous dystocies. The most serious is the last head retention. The authors realized a retrospective study concerning 347 patients who had given birth to a newborn child in breech presentation during a period of 4 years. RESULTS: The vaginal delivery was associated in a significant way to an excess of obstetric traumatisms (5.5%) versus caesarean section (0.5%) and this even after strict selection of vaginal delivery's conditions (P = 0.00453). The rate of the newborn child having Apgar's score < 7 in 5 min was higher in case of vaginal delivery (17.39%) than caesarean section's birth (3.48%). Corrected neonatal mortality is higher in the group of vaginal delivery than caesarean section's group (34% versus 0.49%, P = 0.02553). There is no significant difference of maternal morbidity between caesarean section and vaginal delivery group (P = 4.65). Vaginal delivery is associated to an excess of morbidity and neonatal mortality even after strict selection of the candidates of the vaginal delivery.

[Malign Brenner's tumor particularities and coverage].

Brenner's tumour of the ovary is rare, mostly benign. It was described for the first time by Mac-Naughton-Jones in 1898. Von Numers listed the first malign form in 1945 that represents 2 % of tumours. On the basis of a personal report and of 160 cases listed in the literature, we propose to study anatomoclinical and epidemiological elements of this hurt and to study histological particularities and various therapeutic processes. Malignant Brenner's tumour arises mostly in peri and postmenopausal period. Clinical signs are not specific. Histological exam puts the problem of the choice of the histological malignant criteria. Metastasis occurs in half of cases. They are mostly loco-regional. The treatment is essentially surgical. The efficiency of an additive treatment seems to be debatable.
