[Bronchogenic cysts. Importance of infection in adults. Study of 12 cases].

Background: Bronchogenic cyst is a rare congenital malformation and commonly located in the mediastinum and lung parenchyma.

Objective: To determine the clinical characteristics of the patients with diagnosis of bronchogenic cysts, their location and the infectious bacteria when the cysts are infected. The cases were collected from 1 January 2005 to 1 January 2013, in a third level hospital.

[Malignant mesothelioma risk factors: experience in the General Hospital of Mexico].

Background: Malignant mesothelioma is a neoplasm of bad prognosis, it is linked with asbestos contact, but there are cases without this antecedent.

Objective: To investigate the relationship of asbestos exposition and other factors with malignant mesothelioma.

Methods: Retrospective analysis of histologic confirmed cases of malignant mesothelioma, neoplasic familiar history, tobacco smoking, exposure to wood smoke and to asbestos, were annotated in a paired case/control study 1: 1-3 with logistic regression model to identify risk factors for OR.

Solitary fibrous tumor. Clinic and pathological study of 16 cases.

Background: Solitary fibrous tumor (SFT) is a localized fibrous mesothelioma and was originally described as a benign pleural lesion. It is a mesenchymatous lesion that has been found in different structures and tissues of the human organism. It originates from a stromal fibroblastic cell positive to CD4.

[Aggressive angiomyxoma of the vulva. Case report and literature review].

Aggressive angiomyxoma is a rare vulvovaginal, perineal or pelvic mesenchymal neoplasm with a marked tendency to local recurrence but does not metastasize. A case of an aggressive angiomyxoma of vulva in a 39-years-old women with an illness of one year prior to examination, with a slow and progressive growth of the left vulvar region, without other symptoms. During physical examination, a piriform tumor of 15x10 cm was found, located on the left labia majora, soft tissue dependent.

Mediastinal pleomorphic liposarcoma diagnosed by fine needle aspiration biopsy: a case report.

Background: Progress in radiology and pathology for diagnosing mediastinal tumors has R been made in recent decades, thanks to the use of fine needle aspiration biopsy (FNAB) guided by computed tomography, which has replaced mediastinoscopy and open biopsies.

Case: A 66-year-old male had a history o productive coughing with mucopurulent expectoration, progressive dyspnea, arthralgias, myalgias, astenia and adynamia for the previous 3 months. A CT scan and magnetic resonance imaging revealed a poorly limited tumor mass ofheterogeneous den sity in the anterior mediastinum.

Diagnosis of thymolipoma with fine needle aspiration biopsy. Report of a case initially misdiagnosed as liposarcoma.

Background: Thymolipomas are the most outstanding mesenchymal mediastinal tumors although they represent only a small percentage of thymic neoplasms. Their histogenesis remains unsolved, and they are usually benign. Fine needle aspiration biopsy (FNAB) has become the method of choice for the study of mediastinal tumors, including thymolipomas.

[Amniotic fluid embolism direct cause of maternal death. Clinical case report].

Embolic complications in pregnancy are not common, but require prompt attention due to their high mortality, with reports of numbers up to 80% in patients with presence of amniotic fluid embolism. Of the embolic complications, deep vein thrombosis is the most frequent and 15-24% of patients could present with amniotic fluid embolism. In the case of a 42-year-old female who had this syndrome, it was considered an obstetric catastrophe.

Human herpesvirus-6 has no apparent influence on course of HCV hepatitis, but may complicate HBV hepatitis and alcoholic liver disease. A pilot study.

Human herpesvirus-6 (HHV-6) is a widespread virus with occasional reactivation and a potential hepatotropism. The present study was undertaken to investigate the frequency of HHV-6 reactivation in viral (HCV, HBV) and alcoholic liver diseases and its implication for the course of the primary disease. Serological and immunohistochemical tests were done to document viral activity, hepatocellular apoptosis or proliferation, and autoantibody formation.
