To the best of our knowledge, this is the 49th documented case of primary leiomyosarcoma of bone outside the facial skeleton. This exceptional tumor arises more commonly in adults (mean age: 53 years) and in the long bones of lower limbs, near the knee. The most frequent symptom is pain with or without swelling or fracture. Radiological findings invariably consist of a non specific osteolytic lesion. Although their histological appearance does not differ from that of extraosseous leiomyosarcomas, their diagnosis is difficult and often requires immunohistochemical and/or ultrastructural study. From a practical point of view, the diagnosis of primary leiomyosarcoma of bone also requires an intensive review of the case history and of previous pathology. This is necessary in order to eliminate an extraosseous primary site (mainly in uterus, gastrointestinal tract and soft tissues).

This allowed us to identify 5 clinico-pathological patterns which could occur simultaneously. In most cases, viral proteins or viral genome were identified using immunocytochemistry or in situ hybridization. Multifocal encephalitis involves predominantly the white matter and is likely to be due to haematogenous spread of the infection. Ventriculitis may have variable appearance according to the course of the disease. In one incipient case, the ependymal lining appeared irregular with foci of infected ependymal cells some of which protruded into the ventricular lumen; in other instances, there was acute or chronic necrosis of the ventricular wall with marked vasculitis. Acute haemorrhagic meningo-myelo-radiculitis with necrotising vasculitis may be associated with ventriculitis and results from shedding of infected ependymal cells into the ventricular lumen and secondary seeding of the cerebrospinal fluid. Focal necrotising encephalitis or myelitis usually follows cutaneous herpes zoster in the corresponding dermatoma and is considered to result from neural spread from the diseased trigeminal or dorsal root ganglion. Vasculopathy involving leptomeningeal arteries and causing cerebral infarcts is associated with meningitis in most cases. These findings are in keeping with the observation in other immunocompromised patients, that varicella-zoster virus spread to the central nervous system may follow different routes. Our study tends to show that varicella-zoster virus infection of the central nervous system is more frequent in the acquired immunodeficiency syndrome than previously suspected and suggests this diagnosis must be considered systematically in cases of encephalitis, ventriculitis, focal myelitis, acute myeloradiculitis and cerebral infarcts in these patients, since an efficient treatment is available.</p>","PeriodicalId":75531,"journal":{"name":"Archives d'anatomie et de cytologie pathologiques","volume":"45 2-3","pages":"142-52"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20311540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Guided fine needle puncture in the diagnosis of pancreatic disorders].","authors":"M Fabre,&nbsp;G Amouyal,&nbsp;P Amouyal","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Fine-needle aspiration (FNA) of pancreatic disorders with ultrasound or computed tomographic, and recently echo-endocopic guidance has become commonplace to diagnose the nature of a pancreatic lesion. It is specially usefull in diagnosing solid neoplasms. Most often, FNA is performed to confirm a diagnosis of ductal adenocarcinoma. The aspirate shows cellular clusters with high nuclear-to cytoplasmic ratio, overlapping nuclei and prominant macronucleoli. The cytologic features that permit a diagnosis of neuroendocrin neoplasm are loose cellular aggregates with round nuclei, evently dispersed nuclear chromatin, a moderate amount of amphophilic cytoplasm and rosette formation. Immunocytochemistry can provide additional confirmatory information. Difficulties are encountered in diagnosing cystic neoplasms. The major cytologic differences between serous and mucinous tumors are the absence of mucin and presence of low cuboidal glycogen-containing cells in the microcystic adenoma vs the presence of goblet cells in the mucinous tumors. Except for the presence of necrotic debris, and in the absence of obvious malignant cytologic features, it is impossible to predict the behaviour of mucinous neoplasms. The lower accuracy for cystic neoplasm can be attributed to predominantly bloody specimens and limited cellularity. These problems illustrate the importance of knowing the clinical and radiological features of pancreatic cystic neoplasms.</p>","PeriodicalId":75531,"journal":{"name":"Archives d'anatomie et de cytologie pathologiques","volume":"45 5","pages":"291-8"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20508794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Progressive multifocal leukoencephalopathy used to be a rare condition, usually complicating lymphoproliferative diseases. Since the onset of the AIDS epidemic, its incidence has considerably increased and HIV infection has become, by far, the main risk factor for the disease. In AIDS patients, progressive leukoencephalopathy frequently shows atypical clinical and pathological features. The development of malignant glial tumors, within demyelinating regions, in patients with progressive multifocal leukoencephalopathy, has been reported in exceptional cases. The course of progressive multifocal leukoencephalopathy is invariably fatal. The diagnosis can only be made with certainty by histopathological examination of the brain, on cerebral biopsy or at postmortem. However, neuroradiological features may be extremely suggestive in many cases and PCR seems to be a reliable technique for demonstrating viral genome in the CSF. A few antiviral treatments have been proposed, however their efficacy is difficult to assess due to the low prevalence of the disease and the occurrence of rare cases with spontaneously prolonged survival.</p>","PeriodicalId":75531,"journal":{"name":"Archives d'anatomie et de cytologie pathologiques","volume":"45 2-3","pages":"127-34"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20311575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
