Benign neoplasm of the endobronchial tree is quite rare, while endobronchial lipoma is extremely rare. The irreversible pulmonary damage is due to progressive bronchial obstruction; even so, pleural empyema is exceptionally encountered in a case of endobronchial lipoma. We report a case of a 47-year-old man who had left lung pneumonia with hemoptysis. The chest computed tomography showed cystic...

Human bronchioloalveolar carcinoma (BAC) is a lung cancer, morphologically similar to an endemic contagious lung neoplasm of sheep called sheep pulmonary adenomatosis (SPA) or jaagsiekte. SPA is caused by an exogenous type B/D retrovirus (jaagsiekte sheep retrovirus (JSRV)), which prompted the present study to obtain evidence of a retrovirus in BAC. A panel of 249 human lung tumours, 21 nontumo...

While trials of systemic thrombolysis for submassive and massive pulmonary embolism (PE) report intracranial haemorrhage (ICH) rates of 2%-3%, the risk of ICH in patients with recent brain surgery or intracranial neoplasm is unknown since these patients were excluded from these trials. We report a case of massive PE treated with systemic thrombolysis in a patient with recent neurosurgery for an...

We present a case of a scapular stress fracture in a 17-year-old athletic male that was initially thought to be a neoplasm. Radiographs showed a lesion at the neck of the glenoid with aggressive features. A subsequent MRI and bone scan supported a diagnosis of either tumor or infection. However, before a scheduled bone biopsy, a screening chest CT for pulmonary metastases revealed features of a...

background: clinical and epidemiological variation was seen between the colon cancer (cc) and rectum cancer (rc). so, there is not so much data available about the epidemiological and clinicopathological differences and prognostic factors regarding to cc and cr in iran, we aimed to perform this study. methods: all cases of cc and rc referred to oncology and gastroenterology wards of taleghani g...

BACKGROUND Pulmonary glandular papillomas are rare neoplasms, and their very slow or absent growth over time generally facilitates establishing the diagnosis. CASE PRESENTATION In an 84-year-old woman who underwent surgery for sigmoid colon cancer, a growing solitary pulmonary nodule was identified on postoperative follow-up computed tomography. A computer tomography-guided needle biopsy was ...

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare neoplasm of vascular origin. There are three different major imaging patterns identified in thoracic manifestation of epithelioid hemangioendothelioma: (1) multiple pulmonary nodules; (2) multiple pulmonary reticulonodular opacities; and (3) diffuse infiltrative pleural thickening. Radiographically, presence of bilateral multiple nodule...

A 47-year-old man experienced recurrent pulmonary embolism resistant to aggressive medical and surgical prophylaxis. Although paraneoplastic hypercoagulability was suspected, no endoscopic or radiologic signs of malignancy were detected. Death was the result of electromechanical dissociation, which was attributed to right ventricular outflow obstruction. At autopsy, anaplastic lung carcinoma wa...

While an association between blood eosinophilia and endomyocardial disease has been recognized, the role of the eosinophil in the pathogenesis of the cardiac lesions remains uncertain. In a 69-year-old-man with large cell carcinoma of the lung, marked eosinophilia was stimulated by and progressed with the course of the neoplasm which was producing an eosinophil chemotactic factor. Peripheral bl...
