[Clinical aspects and management of scrotal calcinosis]. / Aspects cliniques anatomopathologiques et prise en charge de la calcinose scrotale.

INTRODUCTION: Scrotal calcinosis is a benign idiopathic cutaneous calcinosis characterized by the presence of calcified nodules of the scrotal skin. The aim of the study is to report the clinical, histological and therapeutic aspects. PATIENTS AND METHODS: This was a prospective descriptive study from 2014 to 2020 in the department of urology. Patients were included, aged at least 15years, consulting for nodules of the scrotal skin whose clinical and paraclinical assessment concluded to scrotal calcinosis. The variables studied were clinical, paraclinical, therapeutic and evolutionary. Informed consent of the patients and anonymity in the use of scientific photographs were observed. RESULTS: In 6years, 8 cases of scrotal calcinosis were diagnosed and operated on, i.e. 1.3 per year. The average age of the patients was 36.2years. The average age of the lesions was 4.2years, the general condition was good (n=8). The unsightly appearance (n=5), pruritus (n=2), recommendation of the spouse (n=2), psychological trauma (n=5), and fear of cancerous degeneration (n=3) were the reasons for consultation. The lesions were scattered or in clusters. Serologies were positive: HIV (n=2), chlamydia (n=4) and syphilis (n=3). Treatment was surgical (n=8). Histological analysis concluded to scrotal calcinosis. The average hospital stay was 2days. The mean time to complete healing was 19.6days without recurrence. CONCLUSION: Scrotal calcinosis is a benign, rare idiopathic pathology. The treatment is surgical.

[Clinical Cancer Genetics: A guide for the pathologist]. / Les trois temps de la prise en charge oncogénétique : la consultation, l'analyse en laboratoire et le suivi personnalisé.

It is paramount to identify patients whose cancer is associated with genetic susceptibility to the disease, since their long-term management depends on it. Anatomical and molecular pathologists play a key role in the process. Indeed, their diagnosis supports or even sometimes warrants germline genetic testing. For example, a colorectal cancer with mismatch repair protein expression loss suggests Lynch syndrome, while a rare type of renal cell carcinoma with fumarate hydrate expression loss is highly evocative of hereditary leiomyomatosis and renal cell carcinoma syndrome. Similarly, the presence of the T790M EGFR variant before treatment in a non-small-cell lung carcinoma warrants further testing as the variant is likely of germline origin. Patients with suspected genetic susceptibility to cancer are referred to the nearest clinical cancer genetics clinic. The cancer geneticist, assisted by a genetic counsellor, then collects detailed personal and familial information, sometimes feeds them into bioinformatics tools or clinico-pathological scores, decides whether germline genetic analysis is justified, determines which genes should be analysed and prescribes testing. Germline testing is carried out on a blood sample by expert laboratories using next generation sequencing on panels of cancer susceptibility genes. The cancer geneticists then return the result to the patient. When a pathogenic variant is identified, the patient's management is modified, with recommendations ranging from intensified surveillance to risk-reducing surgery. Treatment is sometimes adapted to the pathogenic variant. In addition, relatives can undergo genetic testing, should they wish to know whether they carry the familial variant. In the near future, we expect clinical cancer genetics to move towards strengthened partnerships with molecular pathologists and medical oncologists. Somatic genetic analyses are now routine, at least in metastatic cancer, and a proportion of the tumoral variants identified are actually of germline origin. As for the oncologists, the development of mainstreaming programs where they are allowed to prescribe germline testing under the supervision of a cancer genetics team is unavoidable.

[Thoracic oncology and tumor mutational burden: Towards new challenges for the pathologist?] / Oncologie thoracique et charge tumorale mutationnelle : vers un nouveau défi pour le pathologiste ?

Among the different promising predictive biomarkers in immuno-oncology, the tumor mutational burden (TMB) may soon impose itself in clinical routine practice, in association with PD-L1 immunohistochemistry testing. However, the TMB is used currently in clinical trials only, in particular in the thoracic oncology field. If this biomarker becomes mandatory in the near future, the pathologist will have to respond to new challenges in tight collaboration with the activity of molecular pathology platforms. Given the high incidence of lung cancer in France, this new development could have a strong impact on the daily life of the laboratories. This review addresses the different challenges which could be soon proposed to the laboratories and the pathologists due to the use of TMB assays on a daily practice.

[Creation, implementation and objectives of CARADERM, a national network for rare skin carcinomas - Adnexal neoplasm part]. / Développement, mise en œuvre et objectifs de CARADERM, réseau national cancers cutanés rares ­ partie carcinomes annexiels.

INTRODUCTION: CARADERM is a French national network that includes patients with rare skin adnexal neoplasms. The present paper describes only the adnexal neoplasm part of this network. The primary objective of CARADERM is to improve medical care for malignant skin adnexal neoplasms. A multidisciplinary review group and a centralized pathological review group have been set up. PATIENTS AND METHODS: A dual network of clinicians and pathologists has been set up. Data are recorded in a secure database. RESULTS: The CARADERM network comprises of 38 clinical centres and 22 pathology centres. Between 2014 and 2017, 1598 patients with an adnexal neoplasm were included. Data of interest were documented in 80% of cases. Median patient age was 72 years. Major histological subtypes were sweat gland carcinomas (50%), hair follicle carcinomas (37.7%), and sebaceous gland carcinomas (9.8%). Surgery was the first-line treatment for 81% of patients, including 76.9% with standard surgical margin analysis, and 5.5% with exhaustive margin analysis. 920 patients (57.6%) underwent a national pathology review process. DISCUSSION: The CARADERM network aims at providing assistance in difficult situations concerning diagnosis and care in skin adnexal neoplasms. Analysis of the CARADERM data should allow the creation of a prognostic classification of these rare neoplasms together with recommendations. A national multidisciplinary consensus exists. Translational and therapeutic research is ongoing. CONCLUSION: The CARADERM network is currently recruiting and more data should lead to improved knowledge of these tumours in the coming years.

[Results of the Massive Open Online Course (MOOC) on cancer diagnosis and evaluation of its impact on the perception of the pathology specialty]. / Massive open online course (MOOC) sur le diagnostic des cancers : bilan et évaluation de l'impact sur la perception de l'anatomie et cytologie pathologiques.

The Massive Open Online Course (or MOOC) "Diagnostic Strategies Cancers", was hosted in autumn 2016 on the platform "France Université Numérique" and had two levels of learners: students in the field of health and biology and the general public. Of the 5285 learners in 81 different countries, 1237 (23%) were successfully certified. This MOOC was also integrated into the teaching program of medical students of Paris Diderot University and Paris 13 University. Using anonymous questionnaires before and after MOOC, it has been shown that pathology is less known than other medical specialties. Participation in this MOOC led to a marked improvement in participants' knowledge of the place and role of the pathologist in the diagnosis of cancers. Regarding the students who have followed the MOOC as part of their university course, their comments were very positive, but it is necessary to make substantial adjustments in the amounts and contents of the campus-based courses.

[Analysis and prognostic factors of the specimen of radical prostatectomy in prostate cancer]. / Analyse et facteurs pronostiques de la pièce opératoire après prostatectomie totale pour cancer de la prostate.

OBJECTIVES: Handling and pathologic analysis of radical prostatectomy specimens are crucial to confirm the diagnosis of prostate cancer and evaluate prognostic criteria. MATERIAL AND METHODS: A systematic review of the scientific literature was performed in the Medline database (PubMed), using different associations of the following keywords: prostate cancer; prostatectomy; specimen; handling; pathology; tumor staging; Gleason score; surgical margin; prognosis; frozen section; lymph node; biomarkers. A particular search was done on specimen management and characterization of tissue prognostic factors. RESULTS: Handling of both radical prostatectomy specimen and lymph node dissection is standardized according to international criteria. Although the main histoprognostic factors are still Gleason score, pathologic staging and margin status, these criteria have been refined these last 10 years, allowing to improve the prediction of relapse after surgical treatment. CONCLUSION: The standardization of handling and pathology reporting of radical prostatectomy specimens will be mandatory for treatment uniformization according to risk stratification in prostate cancer and personalization of therapeutic approaches.

[Desmoplastic melanoma: a study of 23 cases at 3 centres in the Bouches-du-Rhône region]. / Mélanome desmoplastique : une série de 23 cas dans trois centres des Bouches-du-Rhône.

BACKGROUND: Desmoplastic melanoma (DM) is a rare form of melanoma, often with atypical and potentially misleading aspects that result in difficult and late diagnosis. Because of the high likelihood of local relapse, practitioners must have a good knowledge of such tumours. PATIENTS AND METHODS: A retrospective study of the activities of 3 centres in the Bouches-du-Rhône region between 1998 and 2010 enabled us to collate 23 cases of DM and analyse the clinical and histological features of the disease as well as patient survival. RESULTS: Fifteen of the 23 patients (65.2%) were male with a median age of 64.4 years. Mean Breslow thickness was 7.56 mm. The numbers of AJCC (American Joint Committee for Cancer) stages I, II, III, IV were respectively 4.1, 66.7, 20.8 and 4.1%. Thirteen patients presented relapse, with a mean time to onset of 21 months. The initial relapse involved the skin in 1 case, the lymph nodes in 2 cases, the organs in 5 cases, the organs and subcutaneous region in 1 case, the organs and lymph nodes in 2 cases, and the organs, lymph nodes and skin in 1 case. DISCUSSION: While DM presents a higher rate of local relapse than classical melanoma, this trend appears to subside in the case of thick DM, in which relapse also involves the lymph nodes and/or organs.

[Multiparametric 3T MRI in the routine staging of prostate cancer]. / L'IRM 3 Tesla multi-paramétrique dans le staging du cancer prostatique en pratique courante.

OBJECTIVE: To analyse the detection ability of a multiparametric 3T MRI with phased-array coil in comparison with the pathological data provided by the prostatectomy specimens. METHODS: Prospective study of 30 months, including 74 patients for whom a diagnosis of prostate cancer had been made on randomized prostate biopsies, and all eligible to a radical prostatectomy. They all underwent multiparametric 3T MRI with pelvic phased-array coil including T2-weighted imaging (T2W), dynamic contrast-enhanced (DCE) and diffusion-weighted imaging (DWI) with an ADC mapping. Each gland was divided in octants. Three specific criteria have been sought (detection ability, capsular contact [CC] and extracapsular extension [ECE]), in comparison with the pathological data provided by the prostatectomy specimens. RESULTS: Five hundred and ninety-two octants were considered with 124 significant tumors (volume ≥ 0.1cm(3)). The general ability of tumor detection had a sensitivity, specificity, PPV and NPV respectively to 72.3%, 87.4%, 83.2% and 78.5%. The estimate of the CC and ECE had a high negative predictive power with specificities and VPN respectively to 96.4% and 95.4% for CC, and 97.5 and 97.7% for ECE. CONCLUSIONS: Multiparametric 3T MRI with pelvic phased-array coil appeared to be a reliable imaging technique in clinical and routine practice for the detection of localized prostate cancer. Estimation of the CC and millimeter ECE remains to be clarified, even if the negative predictive power for these parameters seems encouraging.

[Comparative study of histological results between resection and biopsy of the prostate]. / Étude comparée des résultats histologiques de résection et de biopsies de prostate.

PURPOSE: To evaluate the histological correlation between transuretral resection chips and biopsy cores within a population of patients who underwent resection of prostate (TURP) and prostate biopsies (BPx). PATIENTS AND METHODS: Clinical and tumoral data of 77 patients who had both procedures simultaneously or with a slight delay were collected. According to the presence of prostate cancer (Pca), 4 groups were defined: group 1 (TURP and BPx negative), group 2 (TURP positive, BPx negative), group 3 (TURP negative, BPx positive), group 4 (TURP and BPx positive). Means and proportions were compared using Anova and χ(2) test, respectively. RESULTS: The patients were older in groups 3 and 4 (79 and 76 respectively, P=0.65). The PSA was higher in the groups 3 and 4 (64 and 55 ng/mL) than the groups 1 and 2 (10.6 et 16 respectively, P=0.23). The number of positive biopsy was higher in the group 4 than the group 3 (5.6 vs. 4.6, P<0.0001), the chips were more invaded in the group 4 than the group 2 (41% vs. 11% P<0.0001), the Gleason score at TURP was higher in the group 4 than the group 2 (7.5 vs. 6.2 P<0.0001). CONCLUSION: Our study underlines that the Pca of transition and peripheral zones seems to have distinct characteristics. When chips of TURP and BPx were both invaded, it was due to an aggressive cancer. The decision to explore the peripheral zone in the case of positive TURP must take clinical context into consideration.

[Pathologic analysis of upper tract urothelial carcinomas: state of the art review for the yearly scientific report of the French National Association of Urology]. / Anatomopathologie des tumeurs de la voie excrétrice urinaire supérieure: état de l'art pour le rapport annuel de l'Association française d'urologie.

PURPOSE: Upper tract urothelial carcinomas (UTUC) are rare tumors. Pathologist have a crucial role in establishing the diagnosis and the evaluation of the prognosis of these tumors. MATERIAL AND METHODS: A systematic review of the scientific literature was performed in the Medline database (PubMed) using different associations of the following key words alone or concomittantly: ureter; renal pelvis; urothelial carcinoma; specimen; pathology; histology; classification; grade; stage; prognosis. A particular search was done on the characteristics of the specimen management provided by urologists to pathologists and main prognostic specificities expected in UTUCs. RESULTS: Urinary cytology and biopsies are useful to provide the grade of the tumor according to the WHO classification 2004. The urologist needs to depict the clinical context to the pathologist in order to eliminate differential diagnosis. The main prognostic informations provided by the pathologist from the specimen analysis are the following: stage (TNM 2009), grade (WHO 2004), carcinoma in situ, location within upper tract, multifocality, necrosis, tumor size, lymphovascular invasion, margins and potentially microsatellite status when a HNPCC case is suspected. CONCLUSION: The pathologic analysis of a UTUC specimen needs nowadays to fulfill standardised international criteria of quality. However, specific additional aspects reported in the literature (e.g., lymphovascular invasion) are not systematically depicted.

[The accreditation of a surgical pathology and somatic genetic laboratory (LPCE, CHU of Nice) according to the ISO 15189 norm: Sharing of experience]. / L'accréditation selon la norme ISO 15189 d'un laboratoire de pathologie et de génétique somatique (LPCE, CHU de Nice) : retour d'expérience.

Accreditation is going to be vital and unavoidable in the medium term for medical biology laboratories in France. This accreditation will certainly condition the authorization to conduct biological testing in the health care system. All the biological specialities are now affected by this procedure, including the somatic genetics. The anatomo-pathology, which is a medical speciality in France, may be also concerned by the accreditation. However, the nature and the practices of this specialty increase the complexity of this approach to be implemented according to the standard requested by the authorities, i.e. the ISO 15189 normative standard (standard on "specific requirements for quality and competence for medical biology analysis laboratories"). The present article recounts the experience of a hospital laboratory (LPCE, Nice University Hospital) composed of a surgical pathology and a somatic genetics unit: (1) in the accreditation process according to the ISO 15189 standard, (2) at the time of the audit made by the team of "COFRAC" evaluators, and, (3) in evaluating the strategy implemented following the audit.

[Occult primary MALT lymphoma of the breast diagnosed and treated by reduction mammaplasty. An exceptional case report and review of the literature]. / Lymphome du MALT primitif du sein découvert fortuitement et traité par la réduction mammaire. À propos d'un cas exceptionnel et revue de la littérature.

Primary Mucosa-associated Lymphoid Tissue (MALT) lymphoma of the breast is a very rare disease. We report here a case of occult primary MALT lymphoma of the breast diagnosed from a mammaplasty specimen. Primary tumor resection during the mammaplasty surgery was the only treatment of this lymphoma, and there was no recurrence at five years. The clinical and radiologic presentation of primary MALT lymphoma of the breast is similar to epithelial breast carcinoma, and the main diagnostic criteria are microscopic examination and immunohistochemistry. The prognosis of breast primary MALT lymphomas is good after local treatment by surgery and/or radiotherapy, and surgery shouldn't be too aggressive. In this case, no other treatment was indicated after the first surgical procedure. To our knowledge, this is the first case report in the literature of occult primary MALT lymphoma of the breast diagnosed from a mammaplasty specimen. This allows us to highlight the need for systematic microscopic examination of mammaplasty specimens conducted by an experienced pathologist, especially as preoperative examinations are not able to detect all occult breast carcinomas.

[Transbronchial lung cryobiopsy in interstitial lung diseases]. / Les cryobiopsies pulmonaires transbronchiques dans les pneumopathies infiltrantes diffuses.

In some cases of interstitial lung disease (ILD), clinical and biological findings associated with CT scan pattern during multidisciplinary discussion (MDD) fail to yield a confident diagnosis. In these cases, histology may be necessary. Transbronchial lung cryobiopsy (TBLC) is a bronchoscopic procedure that has been developed in recent years and currently contributes to diagnostic work-up in patients with ILD. TBLC provides tissue samples for histological analysis with an acceptable risk of complications, consisting mainly in pneumothorax or bleeding. In addition to higher diagnostic yield than conventional forceps biopsies, the procedure shows a better safety profile than surgical biopsies. The indication to perform TBLC is decided during a 1st MDD and during a 2nd MDD, results can provide a diagnostic yield approximating 80%. TBLC appears to be an attractive, minimally invasive technique to be proposed as a first-line procedure in selected patients in experienced centers, while surgical lung biopsy may be considered as a second-line solution.

[Echographic Aspects Suspicious Of Malignity Of Thyroid Nodule]. / Aspects Echographiques Suspects De Malignite Des Nodules Thyroïdiens.

INTRODUCTION: Thyroid nodules are distressing pathology because of the fear of malignant tumor. It is a common condition but often overlooked by patients. Surgery has an essential place in the treatment, but its performance is correlated with ultrasound data. The objective was to report the probable malignant characteristics of thyroid nodules through ultrasound analysis. PATIENTS AND METHOD: This was a descriptive and analytical retrospective study over a period of 6 years, carried out in the department of Oto-Rhino-Laryngology and Cervico-Facial Surgery of the Hospital Center of Soavinandriana Antananarivo Madagascar. Were included, patients with a cervical ultrasound result preceding the thyroidectomy and an anatomopathologic result of the surgical specimen. The parameters studied were the epidemiological profiles, the clinical data, the ultrasound data, the biological assessments and the anatomopathological results. RESULTS: We listed 150 patients whose mean age was 46.56 years and a sex ratio of 0,11. The malignant thyroid nodule was found in 17 patients or 11,33% of cases. The significant ultrasound aspectsin favor of a malignant thyroid nodule were respectively: poorly limited character [p=0.0002], hypoechoic appearance [p=0.0087], hypervascularization [p=0.0094]. The other moderately suspicious ultrasound characters were represented by the presence of tiny calcification [p=0.2185], the existence of satellite cervical adenopathy [p=0.1982] and peripheral halo [p=0.4502]. The histological type of malignant nodule was dominated by papillary carcinoma (58.82%) and gallbladder carcinoma (23.52%). The ultrasound and pathological concordance was 62.66% of cases. CONCLUSION: The precise description of a thyroid nodule provided by ultrasound is essential in the management of a nodular goiter.

INTRODUCTION: Les nodules thyroïdiens sont des pathologies angoissantes à cause de la hantise d'un cancer. C'est une affection fréquente mais souvent négligée par les patients. La chirurgie a une place incontournable dans la prise en charge mais sa réalisation est en corrélation avec les données échographiques. L'objectif était de rapporter les caractéristiques probables de malignité des nodules thyroïdiens à travers une analyse échographique. PATIENTS ET MÉTHODE: Il s'agissait d'une étude rétrospective descriptive et analytique sur une période de 6 ans, réalisée dans le service d'Oto-Rhino-Laryngologie et Chirurgie Cervico-Faciale du Centre Hospitalier de SoavinandrianaAntananarivo Madagascar. Ont été inclus, les patients ayant un résultat d'échographie cervicale précédant la thyroïdec-tomie et un résultat anatomopathologique de la pièce opératoire. Les paramètres étudiés ont été les profils épidémiologiques, les données cliniques, les données échographiques, les bilans biologiques et les résultats anatomo-pathologiques. RÉSULTATS: Nous avons répertorié 150 patients dont l'âge moyen était de 46,56 ans et unsex- ratio à 0,11.Le nodule thyroïdien malin était retrouvé chez 17 patients (11,33%). Les échostructures significatives en faveur de malignité étaient le caractère mal limité [p=0,0002], l'aspect hypoéchogène [p=0,0087], l'hypervascularisation [p=0,0094]. Les autres caractères échographiques moyennement suspects étaient représentés par la présence de microcalcification [p=0,2185], l'existence d'adénopathie cervicale [p=0,1982] et d'un halo périphérique [p=0,4502]. Le type histologique de nodule malin était dominé par le carcinome papillaire (58,82 %) et le carcinome vésiculaire (23,52 %). La concordance échographique et anatomopathologique était de 62,66 % des cas. CONCLUSION: La description précise d'un nodule thyroïdien fournie par l'échographie est indispensable dans la prise en charge de cette pathologie.

[Management Of Colonic Pseudotumor Anecdotal In Peace Hospital Of Ziguinchor]. / Une Pseudotumeur Colique Anecdotique Pris En Charge A l'Hopital De La Paix De Ziguinchor.

Colonic pseudotumors secondary to fishbone perforation are rare and not easily diagnosed, as the clinical presentation is often misleading. We report the case of a 61-year-old man patient with no medicalhistory, whose clinical picture was in favor of a colonic tumor. The diagnosis of colonic perforation by fishbone was not possible preoperatively due to lack of CT scan. The diagnosiswas made intraoperatively by the visualization of a colonic perforation by fishbone. Pathological examination of the surgical specimen confirmed the inflammatory pseudotumor of the colon without histological sign of malignancies.

les pseudotumeurs coliques secondaires à une perforation par arête de poisson sont rares et ne sont pas de diagnostic facile, car le tableau clinique est souvent trompeur. Nous rapportons le cas d'un patient de 61 ans, aux antécédents d'épigastralgie, dont le tableau clinique était en faveur d'une tumeur colique. Le diagnostic de perforation colique par arête de poisson n'a pas été possible en pré opératoire par faute de scanner. Le diagnostic a été retenu en peropératoire par la visualisation d'une perforation colique par arête de poisson. L'examen anatomopathologie de la pièce opératoire a confirmé la pseudotumeur inflammatoire du côlon sans signe histologique de malignes.

Histopathological nerve assessment in brachial plexus birth injuries.

In children suffering from brachial plexus birth injuries (BPBI), one major difficulty concerns intraoperative selection of the roots to be used for reconstruction. Between November 2018 and August 2020, surgical qualitative evaluations and pathological quantitative analyses were conducted on 52 roots and 29 distal neural stumps (trunks, divisions, cords, and nerves distal to the neuroma) in 17 patients who underwent brachial plexus reconstruction. For each root, surgeons rated stump quality as "good", "fair" or "avulsed". Neural sections were then sent to pathology to determine percentage intraneural fibrosis under microscopy. Mean root intraneural fibrosis rates were 30.5% (SD 24.9; range, 0-80%), 46.3% (SD 32.6; range, 0-90%) and 24.6% (SD 23.5; range, 0-80%) in the "good quality", "fair quality" and "avulsed" groups, respectively, with no significant differences between groups. In distal neural stumps, the mean intraneural fibrosis rate was 30.9% (SD 24.7). These findings raise the question of conducting frozen section biopsy of neural stumps after neuroma resection to determine surgical reconstruction strategy.

[Borderline ovarian tumours: CNGOF Guidelines for clinical practice - Biopathology of ovarian borderline tumors]. / Tumeurs frontières de l'ovaire. Recommandations pour la pratique clinique du CNGOF ­ Biopathologie des tumeurs frontières de l'ovaire.

OBJECTIVES: Ovarian borderline tumors (OBT) represent a heterogeneous group of lesions with specific management for each histological subtype. Thus, the correct histological diagnosis is mandatory. MATERIAL AND METHODS: References were searched by PubMed from January 2000 to January 2018 and original articles in French and English literature were selected. RESULTS AND CONCLUSIONS: OBT should be classified according to the last WHO classification. Any micro-invasion (foci<5mm) or microcarcinoma (foci<5mm with nuclear atypia and desmoplastic stromal reaction) should be indicated in the pathology report. In case of serous OBT, variants (classical or the micropapillary/cribriform) should be indicated (grade C). The peritoneal implants associated with OBT, should be classified as invasive or noninvasive, according to the extension into the underlying adipous tissue. If no adipous tissue is seen the term undetermined should be used (grade B). In case of mucinous OBT bilateral and/or with peritoneal implants or peritoneal pseudomyxoma a search for primitive gastrointestinal, appendiceal or biliopancreatic tumor should be performed (grade C). In case of OBT, a thorough sampling of the tumor is recommended, with 1 block/cm and 2 blocks/cm in case of mucinous OBT, serous OBT micropapillary variant, OBT with intraepithelial carcinoma or/and micro-invasion. Peritoneal implants should be examined in toto. Omentum without macroscopic lesion should be sampled in 4 to 6 blocks (grade C). In case of ovarian cyst suspicious for OBT, fine needle aspiration is not recommended (grade C). In case of ovarian tumor suspicious for OBT, intraoperative examination should be performed by a gynecological pathologist (grade C).

[A case report of an adult with bronchial mould infection complicated by purulent pleurisy]. / Maladie des moules bronchiques compliquée de pleurésie purulente : à propos d'un cas.

INTRODUCTION: Bronchial mould infection or plastic bronchitis is a rare condition, encountered at any age, but with a predilection for childhood. The clinical diagnosis is made easy by the demonstration of solid, branched expectorations. However, the aetiology is not easy to determine and investigation does not often lead to a pathological diagnosis. CASE REPORT: We report the case of a 24 year-old patient, with a history of pulmonary tuberculosis in January 2016, who had had chronic, persistent, solid and branched expectorations since January 2015. Fibreoptic bronchoscopy revealed thick white secretions plugging the bronchi. Pathological examination of the bronchial plugs showed fibrous tissue infiltrated with predominantly lymphoplasmocytic and histiocytic inflammatory cells. Investigations carried out on the pleura did not establish the aetiological diagnosis. The diagnosis of bronchial mould disease of tuberculous origin complicated by pleurisy was established. Corticosteroid therapy led to a complete regression of the moulds within six weeks. CONCLUSION: The presence of solid and branched sputum should suggest fungal bronchitis and is an indication for bronchoscopy for diagnostic and therapeutic purposes. Early management is important to avoid complications.

Rare histologic types of rectal cancer: A monocentric cases series report.

PURPOSE: There is paucity of data on rectal cancer with uncommon histologic types. The objective was to describe managements of care and outcomes in patients with rectal cancer of histologic types other than adenocarcinoma. MATERIAL AND METHODS: This monoinstitutional retrospective study included all patients with rectal cancer undergoing rectal radiotherapy. RESULTS: From 2004 to 2015, 744 patients were treated for rectal cancer, and ten had a histologic type other than adenocarcinoma. The median age was 60.7 years (range: 34.6-80.4 years). Histologic types were neuroendocrine (four), adenosquamous (one), undifferentiated with large cell (one), clear cell (one), anaplastic with small cell (one), signet ring cell (one) and adenocarcinoma with choriocarcinomatous differentiation (one). Four patients were initially diagnosed with a stage IV rectal cancer, and two ultimately became metastatic. Six patients underwent surgery, with four neoadjuvant chemoradiotherapies. None experienced complete response and two had incomplete resections. First-line and concomitant chemotherapies were adapted to histology results, mainly with etoposide and platinum salts for neuroendocrine and small cells tumours. Four patients experienced progression before first line treatments were achieved. Median progression free survival and overall survival were 3.8 and 10.1 months respectively. Two patients were long survivors (22 and 54.7 months, both still alive). All other died of rectal cancer. CONCLUSION: The present study highlights the rarity and the specificities of uncommon histologic types of rectal cancer. We report the real-life management and outcome of rare histologic types of rectal cancers, with dismal prognosis of stage IV tumours. We also report that treatments were adapted to histology.

[WHO classification of head and neck tumours 2017: Main novelties and update of diagnostic methods]. / Classification de l'OMS 2017 des tumeurs de la tête et du cou : principales nouveautés et mise à jour des méthodes diagnostiques.

The publication of the new WHO classification of head and neck tumours in 2017 brought major modifications. Especially, a new chapter is dedicated to the oropharynx, focusing on the description of squamous cell carcinoma induced by the virus Human Papilloma Virus (HPV), and new entities of tumors are described in nasal cavities and sinuses. In this article are presented the novelties and main changes of this new classification, as well as the updates of the diagnostic methods (immunohistochemistry, cytogenetics or molecular biology).
