In the UK, cervical carcinoma is still the eleventh most common cause of cancer in women--it comprises 2% of all female cancers, and accounts for 927 deaths in 2002 alone. The most effective treatments to date are surgery in the form of loop excision of the transformation zone (LLETZ) for pre-invasive disease, LLETZ or simple hysterectomy with laparoscopic pelvic lymphadenectomy for International Federation of Gynecology and Obstetrics (FIGO) Stages IA1 and IA2 microinvasive carcinomas, and Wertheim's hysterectomy or Coelio-Schauta for FIGO Stage IB disease along with concurrent chemoradiotherapy in patents with at least FIGO Stage IB disease. However, radical trachelectomy, which involves a radical excision of the cervix with simultaneous laparoscopic or extraperitoneal lymphadenectomy, may be used selectively in patients with up to FIGO Stage IB1 cancers, as this may preserve fertility in younger women. This paper briefly discusses the role of human papilloma viruses (HPV) and human immunodeficiency virus (HIV) in the development of cervical pre-cancer, and some of the improvements in the techniques used in the cervical carcinoma screening programme. In addition, the diagnosis, staging, spread and prognostic factors involved in invasive cervical carcinoma are mentioned. We will also discuss the role of immunohistochemistry in the diagnosis of invasive cervical carcinoma and recent advances in the molecular pathology of cervical carcinomas.
AIMS: We present the histopathological findings of a series of six cases of a benign uterine smooth muscle tumour with an unusual growth pattern. METHODS AND RESULTS: All cases have the appearances of the recently described dissecting (cotyledonoid) leiomyoma. In addition, three of these lesions demonstrate the features of intravenous leiomyomatosis with varying degrees of hydropic degeneration. CONCLUSIONS: This combination of phenotypes has not previously been described within the literature; therefore we propose that these are classified as examples of 'cotyledonoid hydropic intravenous leiomyomatosis', a new variant of unconventional leiomyoma.
The aim of this work was to investigate the suitability of a novel forward-viewing intravascular ultrasound (IVUS) technique for three-dimensional imaging of severely stenosed or totally occluded vessels, where the conventional side-viewing IVUS systems are of limited use. A stiff 3.8 mm diameter forward-viewing catheter was manufactured to scan a 72 degrees sector ahead of its tip. Conical volume data were acquired by rotating the catheter over 180 degrees by means of a motorised mechanical system. Operating at 30 MHz, the catheter was integrated with an IVUS scanner and a radiofrequency data acquisition system. Postmortem carotid and femoral arteries were scanned in vitro. Correlation of the reconstructed images with histology demonstrated the ability of this forward-viewing IVUS system to visualise healthy lumens, bifurcations, thickened atherosclerotic walls and, most importantly, severe and complete vessel occlusions. A rotating-sector forward-viewing IVUS system is suitable for anatomical assessment of severely diseased vessels in three dimensions.
Fatal house fires occur more frequently in Scotland than elsewhere in Great Britain.(1,2) Over the last few years several educational campaigns were initiated to instruct the public in the risk factors associated with such fire fatalities and to promote the installation of functional domestic smoke detectors. An epidemiological survey of house fire deaths in the Lothian and Borders region of Scotland over the first half of the present decade, was carried out to evaluate any changing incidence trends by comparison with a survey of the fatalities from the first half of the previous decade. The impact of such campaigns in reducing house fires appears to be limited.
The histopathologic features of 25 patients with uterine serous papillary carcinoma (USPC) were presented, with particular emphasis on the changes seen in the remaining müllerian epithelium. The mean age at presentation was 68.9 years; 52% of patients were stage III at the time of presentation and 40% died of their disease within 24 months of diagnosis. Histologic assessment revealed: 1) pure serous carcinoma in 56% of patients and mixed differentiation of serous and endometrioid in the remainder; 2) malignant epithelium reminiscent of that of USPC and akin to carcinoma in situ, frequently seen in the remaining endometrium, cervix, and, less commonly, the fallopian tube; 3) residual endometrium that, when identified (11/25 cases), was atrophic in all cases; 4) various types of cervical involvement in 17 cases (68%); 5) tumor within the fallopian tube in three cases (12%); and 6) carcinoma with in situ-like features in five cases (20%). In conclusion, it appears that USPC is frequently associated with malignant epithelial changes (as with carcinoma in situ) in the remaining müllerian epithelium. This finding suggests either a field change or, more likely, a transepithelial tumor spread. The latter theory is preferable, because this type of spread is frequently seen on serosal surfaces in cases of serous ovarian carcinoma. Uterine serous papillary carcinoma is, therefore, biologically more akin to its ovarian counterpart.
The pattern of cervical involvement in 107 endometrial adenocarcinomas was assessed. The cervix was involved in 29%, higher than noted in previous studies. In 40.6%, the lesion was confined to surface endocervical epithelium only; the remainder had cervical stromal involvement. In the majority only small areas within the circumference of the cervix were affected, indicating a need for adequate tissue sampling. In some cases, malignant epithelium was found as a "migrant" within the endocervical canal, entrapped within cervical mucus or applied to surface epithelium, supporting the concept that endometrial cancer spreads by surface contiguity or implantation rather than by deep tissue planes or via lymphatic channels. Our findings reinforce the view that high-grade lesions and histological subtypes such as uterine serous papillary carcinoma are associated with a later presentation, higher stage and poorer prognosis. We have identified atypical changes in endocervical epithelium that may be misinterpreted as cervical involvement, particularly in the form of atypical reserve cell hyperplasia with a micropapillary pattern that may reflect a reaction to the presence of tumor. It is our assertion that the presence of tumor "migrants", and not endocervical surface atypia, is an indicator of increased probability of cervical involvement by endometrial adenocarcinoma (P = 0.015).
This is an unusual presentation of a rare subtype of endometrial adenocarcinoma (villoglandular papillary carcinoma, VGPC) in a 71-year-old woman, which was initially diagnosed on cervical biopsy as being primary cervical VGPC. Loop excision failed to show any evidence of residual disease. Subsequent hysterectomy revealed a localized villoglandular carcinoma involving the uterine fundus and invading the inner one-third of the myometrium, the background endometrium was atrophic. The remaining cervix contained a focus of papillary forming endometrial type adenocarcinoma involving the surface epithelium and the superficial subepithelial glands. In conclusion, VGPC of cervix occurs mainly in young women and can be treated conservatively, pathologists should be cautious in making such a diagnosis in a postmenopausal woman before ruling out a primary endometrial origin.
