Necrotizing fasciitis is a rapidly progressive soft tissue infection extending from the skin to the fascia, resulting in extensive necrosis. It is a very rare but serious complication, with mortality ranging from 10 to 15%. Optimal management involves early diagnosis followed by treatment combining antibiotic therapy and wide surgical removal as soon as possible. Localisation in the breast is uncommon. Although most cases are primary necrotizing fasciitis of the breast, several cases of necrotizing fasciitis have been reported in the post-operative aftermath of breast surgery. We present a case of necrotizing fasciitis of the breast following submammary mastectomy with immediate reconstruction using a pre-pectoral silicone implant, which resulted in multiple organ failure and the death of the patient despite optimal medical and surgical management. This is the first case to occur after immediate breast reconstruction.

BACKGROUND: The COVID-19 pandemic had a profound impact on health-care systems and reduced access to care. This study assays the mid-term effects of the COVID-19 pandemic on breast cancer management over a 2-year-period in a single French Comprehensive Cancer Center.
METHODS: We performed, in a French comprehensive cancer center, an observational study including all patients with newly diagnosed breast cancer between 2019 and 2021. We collected the number of first consultations for breast cancer, the number of breast and axillary surgeries, pTNM and ypTNM cancer staging, the therapeutic sequence (surgery or neoadjuvant chemotherapy as a primary treatment), patients\' age and their place of residence.
RESULTS: In total, 14,772 patients had a first consultation for breast cancer. Among these 9058 breast and axillary surgeries were performed, 1798 patients had neoadjuvant chemotherapy as a primary treatment. During the first COVID-19 lockdown ( March17, 2020-May 10, 2020), we observed a reduction in the number of first consultations for breast cancer and breast cancer surgeries giving respectively a 42.3% and 27% rate of change. Subsequently, we observed a resumption of consultations and surgeries with a slight increase in early 2021 compared to 2019. In addition, we did not find any difference in terms of therapeutic sequence, pTNM and ypTNM stages, age at diagnosis or place of residence between the reference year 2019 and the years 2020 and 2021.
CONCLUSIONS: Our study shows a decrease in activity during the first lockdown of 2020, then a resumption of activity. These reassuring results only concern patients with breast cancer, and are specific to our institution, whose oncology activity was preserved during the COVID-19 pandemic.

The surgical management of breast cancer has been marked by a therapeutic de-escalation from radical surgery to breast conservation and from axillary curage to sentinel lymph node sampling. With regard to breast surgery, the de-escalation of treatment has been largely due to organized screening, which has made it possible to diagnose tumors of smaller volume or at an earlier stage. The indications for conservative surgery have been broadened by the addition of radiotherapy on one hand, and the introduction of adjuvant and neo-adjuvant treatments on the other hand. In an effort to de-escalate surgery, totally non-invasive techniques such as radiofrequency, HIFU (High Intensity Focused Ultrasound) or cryotherapy have been tested. Currently, three trials are underway to evaluate active surveillance, without surgery, in the management of certain low-risk ductal carcinomas in situ (DCIS). Regarding axillary procedures, the sentinel node technique has allowed axillary staging in patients with early breast cancer without clinical or radiological lymph node involvement. Currently, international recommendations (ASCO, NCCN) and the consensus of experts in St Gallen do not recommend additional curage in cases of macro or micrometastatic invasion of the sentinel lymph nodes if the criteria of ACOSOG Z0011 are met. The question now arises as to the relevance of a biopsy of suspected axillary nodes during the initial workup and the usefulness of the sentinel node technique in the case of a negative initial workup.

OBJECTIVE: The Carl Langer muscle is the main anatomical variation of the walls of the axillary area, its incidence being about 7%. The presence of this muscle crossing the anterior edge of the axillary vessels can induce difficulties of exposure, location and dissection during axillary surgery. In addition, it may be responsible for primary lymphedema of the upper limb, venous thrombosis of the axillary vein or thoracic outlet syndrome due to vascular or nervous compression. The objective of this work was to evaluate the state of knowledge on Carl Langer muscle of the gynecology-obstetrics medical residents of the French Eastern Region.
METHODS: All the medical residents enrolled in the specialized diploma in gynecology-obstetrics in the 5 regions (Alsace, Bourgogne, Lorraine, Champagne-Ardenne and Franche-Comté) were questioned by means of a questionnaire sent by e-mail.
RESULTS: From February to March 2021, 94 of the 160 medical residents interviewed answered to the questionnaire. Ninety-one of them (97%) did not know Carl Langer\'s muscle. Three medical residents thought they knew this muscle (3%) but their knowledge was imperfect.
CONCLUSIONS: Our work has highlighted the general lack of knowledge of this anatomical variation, which is relatively frequent, among French gynecology-obstetrics medical residents who are required to examine or perform surgery on this area. This updated review of the literature should optimize the knowledge of the anatomy of the axillary area and consequently its surgery.

OBJECTIVE: Combined aesthetic procedures are an increasing procedure and demands of the patients. The authors have assembled concrete arguments detailing the risks of combined-surgery associating abdominoplasty and mammoplasty relative to abdominoplasty alone. The purpose of this study was to compare abdominoplasty alone versus abdominoplasty combined with breast surgery in terms of short-term complications, in support of surgical choices.
METHODS: Through application of the PRISMA criteria, we have realized a systematic review of the literature from 1969 to April 2015 in English and French languages by searching in MEDLINE®, PubMed central, Embase and Cochrane Library databases.
METHODS: The levels of evidence for each article were evaluated. Statistical analysis of the results was carried out through association parameters including statistical tests and Odds ratios were calculated for each complication when data was available.
RESULTS: We included 32 observational studies that met the inclusion criteria but only four with usable data. We highlighted a combined Odds ratio of respectively 5.35 and 14.71 for major complications in these studies for combined-surgery compared with abdominoplasty alone.
CONCLUSIONS: The results of this systematic review appears in favor of an increase in major complications related to abdominoplasty combined with breast surgery compared to abdominoplasty alone but the level of evidence of included studies is low or moderate. Prospective cohort comparative studies are necessary to provide strong evidence. However, we recommend to avoid this procedure in massive weight loss patients or patients with thromboembolism history.

OBJECTIVE: Breast magnetic resonance imaging (MRI) has attained a solid position in the diagnosis of breast cancer but its benefit is still to be confirmed in the preoperative staging. The authors assessed the impact of preoperative breast MRI on surgical management of breast cancer in two university hospitals.
METHODS: This retrospective review was realized in two university hospitals and concerned all patients with breast carcinoma who had a surgical first therapy. We selected 89 patients who underwent preoperative breast MRI in the period between January 2008 and December 2009.
RESULTS: The sensitivity of breast MRI for detecting breast tumor was 95%. Fourteen percent of patients had a multifocal disease, 10% a multicentric disease and 2% a synchronous bilateral cancer. The correlation of radiological tumor size with histopathological size was r=0.68 in IRM compared to r=0.45 in conventional imaging (P<0.001). Nineteen additional biopsies were performed and 9.9% of false-positive findings were detected. Retrospectively, planned surgical management was altered in 9% of patients, resulted from use of breast MRI. Six patients had conversion of planned breast conservation to mastectomy and two patients underwent contralateral lumpectomy after discover synchronous bilateral cancer.
CONCLUSIONS: Breast MRI was very sensitive for the detection of breast carcinoma and improved local staging in almost 9% of patients. But, low specificity of this imaging requires a systematically validation of additional lesions by biopsy before surgical planning.

OBJECTIVE: Partial mastectomy, augmentation and reduction mammaplasty are often operated on women who are not yet bothered by breastfeeding. The objectives of this study were to evaluate the information given to patients before surgery, and describe difficulties that mothers confront when starting breastfeeding in order to create a reference document about breastfeeding to inform patients who will undergo such surgery in the future.
METHODS: We led one first study to evaluate the surgeons\' practice in the Reunion Island and a second retrospective and descriptive study upon patients.
RESULTS: We encountered the fact that few patients in childbearing age ask for information about breastfeeding before undergoing surgery, but surgeons do not systematically give such information either, even less before partial mastectomy. The impact of surgery on breastfeeding depends on the type of intervention and the surgical technique. Even though breastfeeding is possible, the mean period of breastfeeding after surgery is shorter and the most frequent difficulty encountered is lactation insufficiency, even more after reduction mammaplasty, periareolar incision, and nipple hypoesthesia after surgery.
CONCLUSIONS: The information document that we tried to establish concerning breastfeeding after partial mastectomy, augmentation and reduction mammaplasty, may compensate patients\' lack of information and sums up all the complications described in our study and in the literature.

The surgical site infection occurs within 30 days after surgery. It is the most common complication of surgery, with a rate of 1 to 5% without antibiotic prophylaxis and less than 1% with antibiotic prophylaxis. The toxic shock syndrome (TSS) is a dramatic complication. We report the case 39-year-old woman who presented a life-threatening TSS acquired after breast surgery. We describe the signs and symptoms of this condition as well as treatment principles.
