CONTEXT Pulmonary Langerhans cell histiocytosis is the most common and best known pulmonary histiocytic lesion; however, the realm of pulmonary histiocytic lesions also includes an assortment of uncommon diseases that may exhibit pulmonary involvement. OBJECTIVE To review pulmonary Langerhans cell histiocytosis and other pulmonary histiocytoses to better ensure correct diagnosis and optimal a...

This paper examines morbidity and mortality patterns in interwar England and Wales, using previously under-explored primary archival source materials. These materials help us understand not only what local authorities could and did do, but also the reasons for the marked variations in the ability of different authorities to manage the problem. We identify where and why there were problems and a...

BACKGROUND The aim of this study was to investigate possible cross-infection of Dichelobacter nodosus in Norwegian farms practising co-grazing of sheep and cattle. METHODS Thirteen farms practising co-grazing of sheep and cattle were included in this descriptive study: five farms with a history of severe ovine footrot (Group I) and eight farms with free-stall housing of cattle and signs of mi...

Adenocarcinoma is the most common type of malignant pulmonary tumor, but osseous metaplasia of this tumor is extremely rare. To date, only 21 cases have been reported in the literature worldwide. Here, we report a case of primary pulmonary adenocarcinoma with benign osseous stromal metaplasia in a 60-year-old woman and discuss the pathogenesis of intratumoral ossification and review the relevan...

We report the occurrence of lung cancer in a six months old lamb of Ouled Djellal breed from Algeria. The main clinical sign was a considerable amount of whitish foamy fluid discharge from the nostrils when the animal head was lowered and the rear end was lifted. The post-mortem examination revealed the presence of enlarged, heavy and edematous lungs with diffuse or foci areas, reddish or white...

BACKGROUND Pulmonary adenocarcinoma rarely spreads to the gynecologic tract, and has not been fully reported to metastasize within a leiomyoma. CASE A 47 year-old woman with recurrent pulmonary adenocarcinoma was incidentally found to have a positron emission tomography (PET) avid pelvic mass at the time of restaging. She was also noted to be anemic, and reported significant vaginal bleeding....

Lung cancer is the most common cause of cancer-related death worldwide. A poor overall survival rate of 16% necessitates the need for novel treatment strategies. Mouse models of lung cancer are important tools for analyzing the significance of somatic mutations in the initiation and progression of lung cancer. Of additional importance, however, are animal models of virally induced cancers. JSRV...
