[Diagnosis and treatment of intra-epithelial carcinoma of the uterine cervix. About 124 cases (author's transl)].

The means for diagnosis, treatment and long follow-up of intra epithelial carcinomas of the uterine cervix are assessed by the authors, about 124 cases seen at the Hotel-Dieu de Paris. The diagnosis is given by cytologic means and mostly by colposcopic examination. When the cylindro-pavimental junction (usual initial focus) is seen in totality, direct biopsies always gave an accurate diagnosis. When the junction is not seen, only a diagnostic--conisation can allow a definitive answer. Two types of surgical treatment were applied: amputation of the cervix conservative of menstrual and/or reproductive functions and, hysterectomy led by vaginal or abdominal route. The patients were followed from 1 to 16 years by the triple cytologic, Schiller test and colposcopic examination: none of them showed any recurrence either of intra-epithelial or of invasive type.

[Haemangiopericytomas of the uterus. 4 case histories (author's transl)].

The authors report four cases of uterine haemangiopericytoma. These vascular tumours develop at the expense of the pericytes of Zimmermann. They are very rare since only 64 cases have been reported. The haemangiopericytomas of the uterus are clear cut histologically and as far as their ultrastructure is concerned. They therefore can be clearly distinguished from other connective tissue tumours which develop in the uterus and especially in the stroma of the endometrium. They should be considered as slow growing sarcomata of the myometrium as a study of the embryogenesis of the genital tract shows. Their prognosis is guarded.

Fibrothecomas of the ovary: CT and US findings.

OBJECTIVE: Fibrothecomas of the ovary are mesenchymal tumors representing 4-5% of all ovarian neoplasms. The purpose of this study is to describe a large series of CT findings in this type of tumor. MATERIALS AND METHODS: We reviewed retrospectively the CT examinations in 25 unilateral cases confirmed by surgery and pathology. Unenhanced and enhanced CT scans were performed in all cases and dynamic CT scans were performed in nine cases. These findings were compared to ultrasound in all cases. RESULTS: Computed tomography detected all but two small ovarian tumors (< 2 cm). Eighteen of 23 fibrothecomas were solid, with significant (> 10 HU) enhancement between precontrast and delayed CT scans. In all eight uncomplicated cases, nonincremental dynamic CT scan did not visualize arterial vessels; in seven of nine cases examined dynamically, early uptake of contrast material was visualized. Three of 23 fibrothecomas were partly cystic, partly solid. Two cases with torsion were mainly cystic with thickening and hemorrhage of the tube. CONCLUSION: In conclusion, 79% of ovarian fibrothecomas appeared as solid masses with delayed accumulation of contrast medium. On dynamic CT, the absence of arterial vessels and absence or slight early uptake of contrast enhancement could be useful findings for preoperative diagnosis. When partly or mainly cystic (21% of cases), ovarian fibrothecomas could not be easily differentiated from other ovarian masses.

CT in adnexal torsion with emphasis on tubal findings: correlation with US.

OBJECTIVE: Our goal was to determine the CT and US aspects of the fallopian tube in adnexal torsion. MATERIALS AND METHODS: The CT scans and US studies of 10 patients with surgically proven unilateral torsion of the adnexa were reviewed. RESULTS: On CT the fallopian tube on the involved side was identified in eight cases as an almost tubular or comma-shaped structure extending from the uterine cornua and covering partially the adnexal mass. This tube was significantly thickened and measured 20-40 mm. Hemorrhage (density > or = 50 HU on precontrast CT scans) was present in the tube in six patients. A heterogeneous contrast agent uptake was detected in the tube in five patients. An adnexal mass was visualized on the involved side in all patients, with hemorrhage in the mass in four patients. Peritoneal fluid and/or ileus were present in six patients. On US an echogenic structure that corresponded to the enlarged tube visualized on CT was detected in three cases and an adnexal mass in all cases. CONCLUSION: Thickening of the fallopian tube with hemorrhage could be detected by CT and is suggestive of torsion especially if associated with an adnexal mass.

[Massive edema of the ovary. A clinicopathologic study of one case and review of the literature (author's transl)].

The first observation of a massive ovarian edema with frozen-section examination of a biopsy specimen and ovarian preservation is related. A 27-year-old woman had a 12 cm right ovarian mass on twisted pedicle. After the ovary was untwisted and biopsied and while waiting for the frozen section study, the ovary returned to normal size and aspect. Ovarian preservation was decided. The elements of histopathologic diagnosis, in particular for a frozen-section examination of ovarian biopsy, are listed and discussed. Diagnostic difficulties must be solved by : clinical and peroperative macroscopic findings, a large biopsy specimen, allowing several frozen-section studies, in order to detect ovarian follicles scattered by the edema, which alone allows the affirmation of the diagnosis.

[Surgical treatment of trophoblastic diseases].

Early diagnosis of a developing hydatidiform mole gives an opportunity to evacuate this by intrauterine suction. This atraumatic procedure which is sure in its outcome has considerably lowered the indications for curettage, for hysterectomy and for hysterotomies. On the other hand, when trophoblastic disease persists chemotherapy is indicated so long as the indications are strictly grounded on biological criteria. The real indication for surgery is found when an isolated focus is resistant to medical treatment.

[An original and effective technic for trachelorrhaphy. Preliminary note].

Extensive commissural tears in the region of the isthmus accompanied by incompetence of the cervix can be easily and successfully treated by an original procedure carried out through the vagina. The technique uses at the same time the general ideas and advantages of the freshening of the surfaces technique uses at the same time the general ideas and advantages of the freshening of the surfaces technique of Emmet, the repair of the isthmus technique of Lash and of Palmer and Shirodkar's cerclage technique for stitching the isthmus of the uterus.
