The cell block method increases the diagnostic yield in exudative pleural effusions accompanying lung cancer.

Objective: Thoracentesis is the first investigation to be performed in a patient with lung cancer and pleural effusion. The diagnostic yield of conventional smear studies varies in the first thoracentesis. In this study, we aimed to investigate if the cell block method increases the diagnostic yield in exudative pleural effusions accompanying lung cancer.

Fibrosing mediastinitis mimicking bronchogenic carcinoma.

Fibrosing mediastinitis is a rare but benign disorder characterized by an excessive fibrotic reaction in the mediastinum which can result in compromise of airways, great vessels, and other mediastinal structures. In this paper we presented a patient with fibrosing mediastinitis mimicking bronchogenic carcinoma. The patient was a 32-year-old diabetic male admitting with cough and hemoptysis.

The association of topoisomerase 2α expression with prognosis in surgically resected non-small cell lung cancer (NSCLC) patients.

Background: Topoisomerase 2α (Topo 2α) is a nuclear enzyme that alters the topology of DNA. It's essential for normal chromosome segregation during cellular division. We aimed to investigate the association of Topo 2α expression with clinical, pathological parameters and prognosis in surgically resected non-small cell lung cancer (NSCLC) patients.

Recurrence of thymoma after 11 years presenting as diffuse pleural thickening.

A 50-year-old man presented with a 1-month history of dyspnea, weight loss, and pleuritic chest pain. He had environmental asbest exposure from birth to 12 years-old. Past medical history revealed maximal thymectomy operation and adjuvant radiotherapy with the diagnosis of minimally invasive lymphocytic thymoma 11 years ago.

Crimean-Congo hemorrhagic fever virus in various ixodid tick species from a highly endemic area.

Ticks are major vectors of numerous diseases affecting animals and humans. Presence of various tick-borne pathogens such as Crimean-Congo hemorrhagic fever virus (CCHFV) in various tick species was documented. CCHF is a severe tick-borne illness caused by the CCHFV which is a member of the Nairovirus genus (family: Bunyaviridae).

Waxing and waning pulmonary nodules and myelodysplastic syndrome.

A 53-year-old diabetic woman with the diagnosis of myelodysplastic syndrome was admitted to our hospital with symptoms of anorexia, malaise, fatigue, night sweats, and weight loss. The radiological evaluation revealed waxing and waning pulmonary nodules. A diagnosis of pulmonary tuberculosis was reached by pathologic examination of a wedge biopsy.
