An unusual cause of precordial chest pain.

Extraskeletal chondrosarcoma in anterior mediastinum is very rare. A 45-year-old male patient was admitted to the hospital with precordial chest pain. A large and well-shaped mass in the anterior mediastinum was seen radiologically, and there was a clearly compression of the heart by the mass.

Endobronchial tuberculosis: histopathological subsets and microbiological results.

Background: Endobronchial tuberculosis (EBTB) is defined as a tuberculous infection of the tracheobronchial tree with microbial and histopathological evidence, with or without parenchymal involvement. Bronchoscopic appearances of EBTB have been divided into seven subtypes: actively caseating, edematous-hyperemic, fibrostenotic, tumorous, granular, ulcerative, and nonspecific bronchitic. However, information for establishing a definite microbiological diagnosis in each of these categories is lacking.

Determination of genetic diversity of Vitis vinifera cv. Kabarcik populations from the Coruh Valley using SSR markers.

Northeastern Turkey is recognized as one of the most important germplasm centers for the grape in the world. In the present study, simple sequence repeat markers were used to investigate the genetic diversity between four Vitis vinifera cv. Kabarcik populations sampled from the Coruh Valley in Turkey, at altitudes of 800-1,150 m.

Mounier-Kuhn syndrome: a rare cause of bronchial dilation.

Mounier-Kuhn syndrome, or tracheobronchomegaly, is a rare clinical and radiologic condition characterized by marked tracheobronchial dilation and recurrent lower respiratory tract infections. Diagnosis is typically accomplished with the use of computed tomography and bronchoscopy, as well as pulmonary function testing. Patients may be asymptomatic; however, symptoms can range from minimal with preserved lung function to severe respiratory failure.

Polyostotic fibrous dysplasia of the ribs: An unusual cause of chest pain and dyspnea.

Fibrous dysplasia is a benign bony abnormality that may be monostotic or polyostotic and is not included in the differential diagnosis of chest pain and dyspnea, since it is typically asymptomatic. A 36-year-old man presented with left-sided chest pain and dsypnea for three months. Chest X-ray and chest computed tomography scan revealed a large solid mass arising from the anterior parts of the left fourth, fifth, and sixth ribs and compressing the adjacent lung parenchyma.
