A case is described of a 79-year-old man, trampled by his horses, who subsequently developed a wound infection and, later, meningitis. Streptococcus equi subsp. zooepidemicus was isolated as the causative organism. S. equi subsp. zooepidemicus, which carries the Lancefield Group C antigen, is an uncommon human pathogen but is commonly isolated from bacterial infections in animals, particularly horses. It is most commonly acquired by humans following animal contact. A review of the literature identified 20 previously described cases of S. equi subsp. zooepidemicus meningitis. Crude mortality following infection was 24%. All of the patients who died were over 70 years of age and the ingestion of unpasteurised dairy products was associated with all but one of the fatal cases. Hearing loss was a frequent complication, occurring in 19% of cases. Only 38% of patients made a complete recovery. Treatment regimes commonly included benzylpenicillin or a third-generation cephalosporin, with a mean treatment duration in survivors of 23 days. 相似文献

A 76 year old white woman presented with a four month history of dysphagia and weight loss. Clinical, radiological, and endoscopic examination revealed a pigmented mass in the lower third of the oesophagus. The preoperative diagnosis, including biopsy examination, was that of malignant melanoma. Following oesophageal resection, the mass was found to be a localised, relatively superficial tumour with light, electron microscopic, and immunohistochemical features common to both Schwann cells and melanocytes. The patient survived 46 months after surgery and died of a stroke, with no evidence of tumour recurrence. The tumour is presented as a case of melanocytic schwannoma, with unique features when compared with oesophageal melanotic schwannomas and malignant melanomas described in the literature. The differential diagnosis is discussed and an origin from a common precursor cell of neural crest origin is postulated. 相似文献

Influenza virus infection remains a major cause of morbidity and mortality during winter seasons. Bacterial and virus co-infection is a commonly described situation in these patients. However, data on co-infection by influenza A and B viruses are lacking. In this study, we present the cases of co-infection by influenza A and B viruses during the winter season of 2014–2015 in our institution. We analyzed 2759 samples from 2111 patients and found that 625 samples corresponding to 609 patients were positive for influenza A or B virus. A total of 371 patients had influenza A, 228 had influenza B, and 10 (1.6 %) had influenza A and B virus detection in the same sample. The median age of co-infected patients was 78.6 years, and only one of the co-infected patients died because of the infection. Comparison with a control group of mono-infected patients revealed that co-infection was significantly associated with nosocomial acquisition [odds ratio (OR)?=?4.5, 95 % confidence interval (CI)?=?1.05–19.25, p?=?0.042]. However, co-infection was not associated with worse outcome, previous underlying condition, or vaccination status. Multivariate analysis revealed that co-infection was not an independent risk factor for death and that no single risk factor could predict co-infection. 相似文献

Intravascular synovial sarcoma (IVSS) is an extremely rare tumor with only four well-documented cases in the English literature. All tumors were located in large veins of the lower extremities or trunk in young women except for one case occurring in a 54-yr-old woman. We report here an additional case of IVSS arising from the superior vena cava in a 32-yr-old woman who presented with a cervical mass and superior vena cava syndrome. A fine-needle aspiration biopsy (FNAB) was performed and showed a malignant biphasic tumor with spindle cell and epithelioid components. The tumor cells were negative for CD31, CD34, factor VIII, desmin, smooth muscle actin, and S-100 protein, and had positive staining for vimentin and cytokeratin (AE1/AE3) predominantly in the spindle and epithelial components, respectively. A diagnosis of synovial sarcoma was made and confirmed in a subsequent transvascular biopsy demonstrating chromosomal translocation t(X, 18) by fluorescence in situ hybridization using a dual color, break-apart-style probe for SYT. Although clinically similar to previously reported IVSS, this is the first case arising in large veins of the upper portion of the trunk and diagnosed by FNAB. 相似文献

Large cell neuroendocrine carcinomas (LCNECs) of the stomach are rare and represent only a small percentage of all gastric endocrine tumors. Here we report a case of a rare combination of gastric LCNEC concurrent with gastric adenocarcinoma. A 50-year-old man presented with heartburn sensation for 2 weeks. An endoscopic evaluation revealed a relatively well-demarcated ulcerative elevated lesion at the lower body of the stomach. Grossly, the gastric mass was a 5×4.5 cm-sized ulcerative fungating lesion. Microscopically, two separated lesions were recognized. The main lesion showed neuroendocrine morphology, such as nests and trabeculae. Most of the tumor cells had large, vesicular nuclei with prominent eosinophilic nucleoli, variable amounts of eosinophilic cytoplasm, and immunoreactivity for synaptophysin and chromogranin A. The other lesion was a well-differentiated adenocarcinoma of early gastric cancer type IIa located adjacent mucosa of the main lesion. We diagnosed this lesion as gastric LCNEC concurrent with focal adenocarcinoma, collision type. 相似文献

Behçet’s disease (BD)-like syndrome is an extremely rare situation occurred after Mycobacterium tuberculosis infection and virus infection. We reported a 45-year-old woman who visited our hospital complaining of swollen left ankle, painful genital ulcer, redness in the left eye and skin rash on lower limbs. The patient had a history of pleural tuberculosis and had received anti-tuberculous therapy for one year. Her left cervical lymph node sample demonstrated tubercle bacilli DNA fragmentation. The diagnosis of tuberculous lymphadenitis and Behçet’s disease (BD)-like syndrome were made. This patient’s symptoms remitted following treatment with anti-tuberculous therapy. This case indicates that some microbial infection can trigger the onset of BD-like syndrome in genetically susceptible subjects. However, treatment strategy of BD-like syndrome secondary to infection is totally different from primary BD. The aim of this case report is to present our experience of the different clinical signs and treatment of BD-like syndrome to expedite its early diagnosis in future. Combination of clinical, radiological, immunophenotypic, pathological, and genetic data contribute to improving the rate of diagnosis. 相似文献

Primary breast lymphoma (PBL) is a rare disease accounting for 0.4-0.5% of all breast malignancies. Diffuse large B-cell lymphoma (DLBCL) is the most common histological diagnosis. The clinical presentation of PBLs is usually no different from that of carcinoma. In this paper we review the literature on the clinical presentation, diagnosis, prognostic factors and treatment options of PBL. In the light of the information gained we discuss three patients with primary breast lymphoma (one with a central nervous system relapse) who were treated in our department in the years 2002-2007. In conclusion: there is no consensus on the question of how to best treat PBL: chemotherapy, radiotherapy or combined therapy. However, the last approach to be the most successful one. Due to high incidence of central nervous system (CNS) involvement in PBL patients, many authors strongly believe that patients with aggressive forms of PBL should receive CNS infiltration prophylaxis, even in the early stages, as this may improve the outcome and significantly reduce the risk of a CNS disease relapse. 相似文献

Epipericardial fat necrosis (EPFN) is an uncommon cause of chest pain. Typically manifesting as severe acute chest pain, EPFN can be mistaken for a serious disorder, such as pulmonary embolism or myocardial infarction. We report a case of EPFN, diagnosed tentatively based on clinical and radiographic findings, with documented resolution of the lesion on chest CT. According to our literature search, this is only the second case in which chest CT alone was used to both diagnose the lesion and track its resolution. It is the first documented case diagnosed and followed as such in North America. 相似文献

Ewing’s sarcoma is the second most common pediatric bone tumor. Primary Ewing’s sarcoma occurring in the cerebral cranium is exceptionally rare, with only one reported case of multiple tumor lesions in adolescence to date. We report a case of a 5-year-old male patient with multiple primary Ewing’s sarcomas associated with the cranial bones, the first pediatric case report to date. We also review 71 cases Ewing’s sarcoma involving intracranial extension. The purpose of this article is to provide data concerning the clinical and therapeutic course of multiple primary Ewing’s sarcomas in associated with cerebral cranium. 相似文献
