Surgery of abdominal wall endometriosis associated with clear-cell carcinoma: Case report and review.

Abdominal wall is a rare location for endometriosis, with a reported incidence of parietal endometriosis of approximately 0.03 to 0.4%. It most often occurs in the aftermath of a caesarean section and is associated with pelvic endometriosis in only 5 to 15% of cases. Rare cases of malignant transformation have been described, mainly in the form of clear-cell tumours. We report the case of a 52-year-old patient with a history of endometriosis who presented with a retractile parietal mass at the level of her caesarean scar. Histological analysis confirmed a clear-cell adenocarcinoma (CCC). Few cases of endometriosis - associated CCC are described in the literature. A review of the literature suggests radical surgical treatment combined with adjuvant radio-chemotherapy. However, the prognosis is poor. The aim of this case report is to suggest the diagnosis of malignant transformation in the presence of a rapidly evolving parietal mass in the context of endometriosis and a history of caesarean section.

Local injection of methotrexate ultrasound guided-transvaginal.

Non-tubal ectopic pregnancies can be located in the uterine portion of the tube (interstitial or cornual), in the cervix (cervical), in a cesarian scar, in the ovary, or intra-abdominally. Even though they are rare, they are associated with a high mortality. Invasive surgeries such as cornuectomy and hysterectomy were common to treat them in case of hemorrhage. Thanks to recent advances in imaging techniques, diagnosis of non-tubal ectopic pregnancy is made earlier and conservative management has been developed in order to respect fertility of patients. Beyond these treatments, systemic or local injection of Methotrexate shows very good success. In the article, we aimed to describe the technics of vaginal injection of in situ methotrexate with ultrasound guidance.

Vulvar and vaginal melanomas: A retrospective study spanning 19 years from a tertiary center.

INTRODUCTION: Mucosal melanomas (MM) of the female genital tract are rare a. We aimed to study the prognostic factors of vulvar and vaginal locations of MM. MATERIAL AND METHOD: A multicenter, retrospective cohort study conducted between 01/01/2000 and 01/06/2019. RESULT: Of the 33 patients included 25 (75.8 %) had vulvar (VuM) and eight (24.2 %) vaginal melanomas (VaM). VaMs were deeper: median Breslow index: 17.5mm [3.5-22] versus 4.3mm [0.35-18] (p=0.013). Average follow-up was 24.0±59.8 months. Twenty-six patients (78.8 %) experienced recurrence. Disease-free survival was 52.9 % at 1year (64.7 % for VuM and 14.3 % for VaM) and 8.4 % at 3 years (11 % for VuM and 0% for VaM) (p=0.002). Median time to the first recurrence was 9.01 months [CI95 %: 2.07-56.71]. VaM recurred earlier than VuM (3.12 months [CI95 %: 2.07-12.49] versus 17.72 [CI95 %: 3.58-56.71], p=0.011). VaM had a higher risk of recurrence (HR=5.64 [CI95 %: 2.01-15.82], p=0.001) in multivariate analysis. Overall survival was 88.5 % at 1year (100 % for VuM and 50 % for VaM), and 59.4 % at 3 years (69.3 % for VuM and 25 % for VaM). Women with VaM died earlier: median specific death occurrence of 8.76 months [CI95 %: 6.54-24.72] versus 39.61 [CI95 %: 21.89-209.21], p=0.013 (HR=5.08 [CI95 %: 1.39-18.60], p=0.014). A lesion size ≥3cm was associated with an increased risk of mortality (HR=8.45 [CI95 %: 1.60-44.52], p=0.012). In multivariate analysis, vaginal location remained an independent and predictive variable of a higher risk of specific death (HR=8.56 [CI95 %: 1.95-37.64], p=0.005). CONCLUSION: A vaginal location of MM is associated with a poorer prognosis than a vulvar location.

Non-menopausal Status, High Nuclear Grade, Tumor Size >30 mm and Positive Resection Margins Are Predictors of Residual Tumor After Lumpectomy for Ductal Carcinoma In Situ of the Breast.

AIM: Breast-conserving surgery with radiation therapy is the primary treatment for ductal carcinoma in situ (DCIS). Re-excision is indicated when clear resection margins have not been achieved, although in some cases the procedure may be unnecessary as there is no residual tumor. The purpose of our three-Center retrospective study was to identify predictors of positive re-excision findings following breast-conserving surgery for DCIS. PATIENTS AND METHODS: A total of 285 patients underwent re-excision following conservative treatment for DCIS between 01/01/08 and 12/31/13 at three breast-cancer referral Centers. We conducted a retrospective, comparative review of the factors that differentiated patients with a residual tumor from those without. The study was based on clinical, radiological, surgical and pathological criteria. RESULTS: A total of 180 patients (63%) had residual tumor after conservative treatment. Six factors were predictive on univariate analysis: young age (p=0.025), non-menopausal status (p=0.016), absence of preoperative biopsy (p=0.0029), high nuclear grade (p=0.0181), lesion size >30 mm (p=0.032), and positive surgical margins (p=0.0016). Four factors remained independently predictive on multivariate analysis: non-menopausal status (p=0.0017), high nuclear grade (p=0.0031), lesion size >30 mm (p=0.012) and positive surgical margins (p=0.0013). We calculated a 93% probability of positive re-excision findings if all four factors were combined. On the other hand, if none of the factors were present, the rate fell to 18%. CONCLUSION: In cases of DCIS, where risk factors for both involved lumpectomy margins and recurrence are carefully studied, knowledge of the risk factors for residual tumor can help guide therapeutic choices.
