[Extended pulmonary tuberculosis and immunocompetence: causes and consequences].

Background: Despite scientific advances, extended forms of pulmonary tuberculosis are still relevant. The aim of our study was to determine clinical features and outcome of extended pulmonary tuberculosis in immunocompetent patients.

Methods: Retrospective comparative study including 100 patients HIV negative, presenting pulmonary tuberculosis divided into 2 groups of 50 patients (group1: extended tuberculosis and group2: localized tuberculosis).

Synchronous mantle cell lymph node lymphoma and pulmonary adenocarcinoma: a case report with literature review.

Background And Aims: Coexistence of mantle cell lymphoma and lung adenocarcinoma is extremely rare. The aim of this study is to present the first case of incidental discovery of primary lung adenocarcinoma associated to lymph node mantle cell lymphoma.

Methods: A 45 year-old man, admitted for inguinal mass appeared since three months.

[Pulmonary tuberculosis in smokers].

Introduction: Tobacco smoking and tuberculosis (TB) are two major public health problems, and the former may affect the morbidity and mortality rates for the latter. This study sought to compare the clinical and radiologic aspects of pulmonary TB, as well as outcome, in smokers and nonsmokers.

Methods: This retrospective case control study examined the files of 90 patients in our pulmonary department with active pulmonary TB, 45 of them smokers and 45, nonsmokers.

Castleman's disease: an intrapulmonary form with intrafissural development.

Castleman's disease (CD) is an uncommon, mainly benign, lymphoproliferative disorder of unknown etiology, mostly involving the mediastinum. Parenchymal lung involvement of the disease is exceedingly rare. We describe a case of CD in a 23-year-old woman with a 4-year history of recurring dyspnea and nonproductive cough, whose chest X-ray showed an abnormal shadow of the right hilum.

Pulmonary blastomycosis: a case from Africa.

Pulmonary blastomycosis is an uncommon pathologic condition that is quite rare in Africa compared to endemic regions of Canada and the upper Midwest of the U.S. We describe a 45-year-old patient who complained of productive cough, hemoptysis, and dorsal rachiodynia.

Tuberculosis due to resistant Haarlem strain, Tunisia.

Multidrug-resistant tuberculosis was diagnosed in 21 HIV-negative, nonhospitalized male patients residing in northern Tunisia. A detailed investigation showed accelerated transmission of a Mycobacterium tuberculosis clone of the Haarlem type in 90% of all patients. This finding highlights the epidemic potential of this prevalent genotype.
