Giant angiolipoma of the arm in an elderly patient.

Introduction Angiolipoma is a histological variant of lipoma and is the most common neoplasm in the trunk and extremities of young adults. It is extremely rare in elderly people, and its size is ≤4cm. Few data are available for large angiolipomas. Case History An 86-year-old patient was admitted to our surgical department due to a large mass on his left arm, which was resected. The specimen measured 19.5 × 15 × 10.5cm. Histopathological examination revealed a benign non-infiltrating angiolipoma. This is the first report of a giant angiolipoma of the arm reported in an octogenarian patient. Conclusions Giant lipomas of the upper extremities are extremely rare. Resection is associated with cure in most patients, but regular follow-up should be considered.

Parastomal evisceration as an extremely rare complication of a common procedure.

The creation of an abdominal stoma is a common procedure performed as part of the treatment for many conditions. Common complications include poor stoma siting, high output, skin irritation, ischaemia, retraction, parastomal hernia and prolapse. An extremely rare stoma complication is parastomal evisceration. We present a case of a 48-year-old woman who presented to us with parastomal evisceration as a late complication of a transverse colostomy. It is the second case reported as a complication of this procedure but the first that occurred after such a long postoperative period (almost 18 months).

Screening transvaginal uterine ultrasonography for identifying endometrial pathology in postmenopausal women.

BACKGROUND: During the last decade, transvaginal ultrasonography (TVS) has become a widely-used technique for the evaluation of endometrial histology. The purposes of this study were to compare transvaginal sonographic evaluation of the endometrium with histology obtained by endometrial biopsy in asymptomatic postmenopausal women and to determine whether screening transvaginal sonography might be useful in the evaluation of postmenopausal women. MATERIALS AND METHODS: The study included 59 unselected asymptomatic postmenopausal women who attended the outpatients' clinic for annual cervical cytology at Ioannina University Hospital, Greece. The women were evaluated by transvaginal scans, performed immediately before endometrial biopsy. RESULTS: In the 43 women with a histopathological diagnosis of normal endometrium/inadequate for assessment/atrophy, the mean endometrial thickness was 5.1 +/- 3.3 mm (range 0.8-13.8 mm) whereas the corresponding value in the 16 women with abnormal findings was 17.6 +/- 4.3 mm (range 9.4-24.6 mm) (p<0.001). If a 9-mm cut-off limit was used for endometrial thickness, the sensitivity, specificity and positive predictive value were 100%, 90.69% and 80%, respectively. CONCLUSION: TVS is a sensitive test for determining endometrial disease in asymptomatic postmenopausal women. However, well-designed studies should be conducted, completed, analysed and validated before a mass-screening program using TVS is implemented.

Transvaginal uterine ultrasonography compared with endometrial biopsy for the detection of endometrial disease in perimenopausal women with uterine bleeding.

BACKGROUND: Almost 70% of all gynecological consultations in perimenopausal women are related to irregular uterine bleeding. In this prospective study, we compared endometrial assessment by transvaginal ultrasonography (TVS) in perimenopausal women with irregular uterine bleeding to histological assessment and tested whether the TVS was effective as a diagnostic tool for the detection of endometrial pathology in these women. MATERIALS AND METHODS: Eighty consecutive perimenopausal women complaining of irregular uterine bleeding participated in the study. The women were evaluated by transvaginal scans, performed immediately before endometrial biopsy. The ultrasonographic results were compared with the histological diagnosis obtained from the endometrial biopsy. RESULTS: Sixty-seven out of 80 women (83.7%) had normal histological findings, whereas 13 (16.3%) had abnormal findings. No endometrial cancer was diagnosed in this cohort of women. In the 67 women with a histological diagnosis of normal endometrium, mean+/-SD endometrial thickness was 10.5+/-4.0 mm (range 4.0-18.5 mm), whereas the corresponding value in the 13 women with abnormal findings was 18.7+/-3.8 mm (range 13.5-22.5 mm). If a 13 mm cut-off limit was used for endometrial thickness, which would include all abnormal cases, the sensitivity, specificity and positive predictive values were 100%, 71.64% and 40.62%, respectively. CONCLUSION: TVS can identify women with perimenopausal bleeding in which the likelihood of endometrial pathology is high and in which tissue sampling should be performed. Thus, TVS can be a primary method of selecting women with perimenopausal bleeding who must be further investigated with more invasive methods such as endometrial biopsy.

[Abnormal ramification of the axillary artery: sub-scapular common trunk]. / Ramification anormale de l'artère axillaire: tronc commun sous-scapulaire.

In a man's dissected cadaver we observed an unusual branching of the right axillary artery, which gives a large collateral branch. This branch is the origin of several important arteries as the subscapular artery (with its usual branches), the anterior and posterior circumflex humeral arteries, the proDunda brachii a. and the ulnar collateral artery. The frequency of this variation is evaluated to be 0.45% and is comparable to those found in the literature. We propose to name this artery as common subscapular trunk. The trunk described by us possesses a diameter equal to 6.30 mm and is larger than the continuation or the axillary artery, which courses as superficial brachial artery.

Human papillomavirus testing and the outcome of treatment for cervical intraepithelial neoplasia.

OBJECTIVE: To investigate whether human papillomavirus (HPV) testing could be used in the follow-up after large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia (CIN). METHODS: We performed a retrospective study of 41 women who developed subsequent CIN after LLETZ (group A) and 82 women without CIN for a minimum of 5 years after LLETZ (group B). The first post-treatment cervical smear was retrieved and examined for high-risk HPV deoxyribonucleic acid. The sensitivity, specificity, positive and negative likelihood ratio of HPV testing, first post-treatment Papanicolaou test, and excision margins for the detection of treatment failure were calculated. Multiple logistic regression analysis was also done. RESULTS: The HPV test was positive in 38 of 41 women in group A and 13 of 82 in group B (P <.001). An abnormal cytologic result in the first post-treatment smear was found in 20 of 41 in group A and 11 of 82 in group B (P <.001). Sixteen women in group A and 18 in group B had involved margins (P =.046). Values for the sensitivity, specificity, and positive and negative likelihood ratios of the HPV test were 93%, 84%, 5.8, 0.08; for the Papanicolaou test they were 49%, 87%, 3.9, 0.586; and for margin status they were 39%, 78%, 1.8, 0.782, respectively. Positive HPV test presents significantly high odds ratio for treatment failure (P <.001), independent of cytology and margin status. CONCLUSION: Women who postoperatively have positive HPV testing are at higher risk of treatment failure. This could be performed at the first post-treatment visit and further follow-up could be adjusted accordingly.

Vaginoscopic hysteroscopy and transvaginal sonography in the evaluation of patients with abnormal uterine bleeding.

STUDY OBJECTIVE: To compare accuracy of vaginoscopic hysteroscopy, a new method of outpatient hysteroscopy, with that of transvaginal sonography in diagnosing intracavitary pathology in women with abnormal uterine bleeding. DESIGN: Retrospective comparative study (Canadian Task Force classification II-2). SETTING: Department of gynecology in a tertiary care university hospital. PATIENTS: Three hundred ninety-seven consecutive patients. INTERVENTIONS: Vaginoscopic hysteroscopy, transvaginal sonography, and histologic evaluation of endometrium. MEASUREMENTS AND MAIN RESULTS: Findings at hysteroscopy and sonography were compared with histopathologic results, considered the gold standard diagnosis. Sensitivity, specificity, and positive and negative likelihood ratios were 92%, 95%, 18.4, and 0.08 for vaginoscopic hysteroscopy and 67%, 87%, 5.15, and 0.38 for transvaginal sonography, respectively. CONCLUSION: Vaginoscopic hysteroscopy is quick and well tolerated, and more accurate in detecting intracavitary uterine pathology than transvaginal sonography. More research is required to determine its place in patients with abnormal uterine bleeding, especially premenopausal women.

The use of transvaginal sonography and vaginoscopic hysteroscopy in women on tamoxifen.

BACKGROUND AND OBJECTIVES: Long-term administration of tamoxifen causes endometrial changes. The aim of this study was to evaluate the role of transvaginal sonography and vaginoscopic hysteroscopy in the screening of patients on tamoxifen. METHODS: Seventy patients with breast cancer treated with tamoxifen 20 mg daily underwent transvaginal sonography and vaginoscopic hysteroscopy, a modified relatively painless approach, at the beginning of the treatment and at a follow-up visit approximately 9 months after its initiation. RESULTS: At the follow-up visit, the mean uterine dimensions and mean endometrial thickness as measured by ultrasound were significantly larger, and pulsatility and resistance indices of the uterine arteries as measured by Doppler were significantly lower. Sonography revealed abnormal endometrial thickness in 73% (51 of 70) of the patients, and 83% (58 of 70) had hysteroscopical changes. Sonography missed 1 case of endometrial adenocarcinoma. CONCLUSIONS: Vaginoscopic hysteroscopy, an approach that causes reduced pain, can add significantly to the sensitivity of transvaginal sonography for the detection of endometrial changes in patients with breast cancer receiving tamoxifen. It is recommended for every patient prior to the initiation of treatment and at the follow-up visits.

Replacement of the uterus by malignant mesothelioma of the peritoneum: a case report.

Malignant mesothelioma of the peritoneum is a rare tumor that must be distinguished from the more common primary peritoneal serous epithelial neoplasms. We report a case of a 66-year-old female presenting with weight loss, anemia, and a large pelvic mass on ultrasound. At laparotomy a large (9 x 6.5 x 3.5 cm) mass in the anatomical position of the uterus was found in the minor pelvis. The uterus, tubes and ovaries could not be identified. Palpable paraaortic lymph nodes and liver nodules were found. Immunohistochemically the tumor cells were positive for cytokeratin, epithelial membrane antigen and vimentin-CEA, but S-100 protein and Leu-M1 were negative. Remnants of the uterine corpus, fallopian tubes and ovaries could not be identified. The overall features were best regarded as malignant peritoneal mesothelioma. There have been reports of mesotheliomas involving the uterus. However, this is the first reported case of mesothelioma causing total replacement of the uterus.

Cervical intraepithelial neoplasia outcomes after large loop excision with clear margins.

OBJECTIVE: To identify risk factors for residual or recurrent cervical intraepithelial neoplasia (CIN) after large loop excision of the transformation zone with clear margins. METHODS: We did a case-control study of women treated with loop excision for CIN who had adequate follow-up and in whom margins were believed to be clear. Women with clear margins in whom no subsequent lesions were found (controls) were compared with women who presented with subsequent CIN (cases). Epidemiologic and colposcopic risk factors for recurrence were analyzed. Multiple logistic regression analysis was done to identify independent risk factors. RESULTS: In 31 of 635 women studied (4.9%), subsequent lesions were diagnosed. Univariate analysis identified glandular involvement, satellite lesions, and age over 40 years in cases as significant. Multiple logistic regression analysis confirmed that these three characteristics were independent risk factors, with odds ratios of 4.9 (95% confidence intervals 1.9, 12.3), 19 (7.5, 48.2), and 6.7 (2.8, 15.8), respectively. Subsequent lesions were identified by colposcopy or cytologic testing during the first postoperative year in all but one case. CONCLUSION: Age over 40 years, glandular involvement, and satellite lesions were related to the reappearance of CIN after loop excision with clear margins. These findings could be used to define appropriate follow-up protocols.
