Intravascular lymphoma is a rare form of non-Hodgkin's lymphoma with varied but highly evocative clinical presentations, particularly in terms of dermatology. Histological examination of the skin may be sufficient to allow diagnosis.

Vulvar cancer is a rare disease, which represents 4% of gynecological tumors with an incidence of 0.5 to 1.5 per 100,000 women per year in France. Vulvar cancers are induced in 30 to 69% of cases by the presence of papillomavirus (HPV), in particular HPV 16 and 18, and can also occur in an inflammatory context. The diagnosis is made by histological examination of a vulvar biopsy. The histological subtype is a squamous cell carcinoma in 90% of cases. The 5-year survival of patients with vulvar cancer ranges from 86% for localized stages (FIGO I and II) to 57% for advanced stages (FIGO III and IVA), and 17% in case of metastatic disease (FIGO IVB). The treatment of vulvar cancer is mainly surgical, but radiotherapy and chemotherapy have become more important in recent years. Management has evolved into a personalized multidisciplinary approach, where each therapeutic decision must be discussed in a multidisciplinary consultation meeting. Surgical excision with tumor- free margins is central in the management of early stages. The indication for radiotherapy and brachytherapy should be discussed in the event that the excisional margins are positive in early stages. Radiotherapy is indicated in cases of lymph node involvement or in a neoadjuvant situation if the tumor is not immediately resectable. In this situation, it can be associated with chemotherapy. Chemotherapy alone is the treatment of diseases that are metastatic at the time of diagnosis.

Among the 20,000 new cases of head and neck neoplasms in France each year, squamous cell carcinomas (HNSCC) represent about 90 % of the cases. Among these, variants of conventional squamous cell carcinomas represent between 5% and 10% of cases. Patient history and risk factors are often similar from those of conventional HSNCC. Variants may, however, be misdiagnosed, which can lead to therapeutic mismanagement due to confusion with sarcomas, glandular tumors or even benign tumors. Diagnostic workup needs to be more cautionary or to include additional exams not to omit their most aggressive component in the case of composite tumors or to under stage the tumor. Immunohistochemistry and specific molecular analyses may be required for proper diagnosis. Central pathological review may also be essential for some of these variants. In addition, some variants are radioresistant and, conversely, others are radiosensitive. An update of the REFCOR 2008 standards was carried out in the light of the international literature and the 2017 WHO/IARC classification for the seven main variants of HNSCC, verrucous, acantholytic (to be named adenoid carcinomas), basaloid, papillary, spindle cell (incorrectly named sarcomatoid), adenosquamous and lymphoepithelial carcinomas.

Triples negative breast cancer defined by the absence of expression of the hormone receptors and HER2 protein, are considered as aggressive tumours with bad outcome in comparison to the hormone sensitive tumours. The aim of the study was to evaluate the link between hormone factors and prognostic factors of triple-negative tumours.

Salivary gland-like tumours are described in the breast but remain very rare and difficult to diagnose in this location. Only 37 cases of mucoepidermoid carcinoma have been described in the literature. We report the challenging diagnosis of a mucoepidermoid carcinoma sampled by core biopsy in a 51-year-old woman.

PELICAN ("Partager Efficacement en Laboratoire les Informations des Comptes rendus ANatomopathologiques") is a software, which generates standardized reports, and allows to automatically create a database. It has been used in central nervous system tumor pathology at the University Hospital of Nancy since 2014. The purpose of this article was to illustrate the use of this application for meningiomas, with a first statistical evaluation.

Endocrine treatment represents the cornerstone of endocrine-sensitive pre-menopausal early breast cancer. The estrogen blockade plays a leading role in the therapeutic management with surgery, radiotherapy and selective antiestrogen treatment. For several years, selective estrogen receptor modulators, such as tamoxifen, have revolutionized medical care of hormone receptors-positive breast cancer and have conquered the therapeutic arsenal while becoming the gold standard of treatment. Other combinations associating the ovarian function suppression using LHRH agonists with tamoxifen or aromatase inhibitors have been recently investigated, leading to mitigated opinions regarding the clinical benefit of these associations. We propose here a comprehensive overview on existing data and their actualization concerning LHRH analogues, whilst emphasizing benefit-risk balance for this targeted population.

Faced to an undetermined ovarian mass on ultrasound, an MRI is recommended and the ROMA score (combining CA125 and HE4) can be proposed (grade A). In case of suspected early stage ovarian or fallopian tube cancer, omentectomy (at least infracolonic), appendectomy, multiple peritoneal biopsies, peritoneal cytology (grade C) and pelvic and para-aortic lymphadenectomy are recommended (grade B) for all histological types, except for the expansive mucinous subtype where lymphadenectomy may be omitted (grade C). Minimally invasive surgery is recommended for early stage ovarian cancer, if there is no risk of tumor rupture (grade B). Adjuvant chemotherapy with carboplatin and paclitaxel is recommended for all high-grade ovarian or Fallopian tube cancers, stage FIGO I-IIA (grade A). In case of ovarian, Fallopian tube or primitive peritoneal cancer of FIGO III-IV stages, thoraco-abdomino-pelvic CT scan with injection (grade B) is recommended. Laparoscopic exploration for multiple biopsies (grade A) and to evaluate carcinomatosis score (at least using the Fagotti score) (grade C) are recommended to estimate the possibility of a complete surgery (i.e. no macroscopic residue). Complete medial laparotomy surgery is recommended for advanced cancers (grade B). It is recommended in advanced cancers to perform para-aortic and pelvic lymphadenectomy in case of clinical or radiological suspicion of metastatic lymph node (grade B). In the absence of clinical or radiological lymphadenopathy and in case of complete peritoneal surgery during an initial surgery for advanced cancer, it is possible not to perform a lymphadenectomy because it does not modify the medical treatment and the overall survival (grade B). Primary surgery is recommended when no tumor residue is possible (grade B). After a complete first surgery, it is recommended to deliver 6 cycles of intravenous (grade A) or to propose intraperitoneal (grade B) chemotherapy, to be discussed with patient, according to the benefit/risk ratio. After a complete interval surgery for a FIGO III stage, the hyperthermic intra peritoneal chemotherapy (HIPEC) can be proposed in the same conditions of the OV-HIPEC trial (grade B). In case of tumor residue after surgery or FIGO stage IV, chemotherapy associated with bevacizumab is recommended (grade A).

The objective of our study was to evaluate, in a review of the literature, the impact of diagnostic ureteroscopy before total nephroureterectomy (NUT) on the risk of bladder recurrence.

Improved knowledge of sentinel node procedures coupled with the results of adjuvant clinical trials in stage III melanoma have prompted the French Cutaneous Oncology Group to propose new guidelines for the management of stage III melanoma. These guidelines comply with the principles of the evidence-based medicine.
