Primary tracheal schwannoma

Primary neurogenic tumors of trachea are extremely uncommon and account for only about 9% of all neoplasms of trachea. Tracheal schwannoma is among the rarest of them and there is no unanimity of opinion regarding its treatment. We report a 30 year-old woman with symptoms of airway obstruction due to primary tracheal schwannoma. She was suffering from cough and exertional dyspnea. She was admitted to the thoracic surgery ward with stridor and hemoptysis and underwent rigid bronchoscopy and biopsy. The patient then underwent primary tracheal resection and anastomosis through a cervicomediastinal approach. The diagnosis was made through histopathological examination as schwannoma

Primary pulmonary hemangiopericytoma: a case report

Hemangiopericytoma is a mesenchymal neoplasm originating from the pericyte, a cell type that surrounds the capillaries. Its primary localization in the lung is extremely rare. A 70-year-old woman was referred to our hospital complaining of cough and non-massive hemoptysis from 2 months earlier. She was a nonsmoker with a history of close contact with sheep and a dog. On physical examination, she had reduced respiratory sounds in the left upper zone. Her chest x- ray revealed a mass in the left middle and upper zones. CT-scan of the lungs revealed a parenchymal mass with -4 to 20 [HU] densities. Hemagglutination test was negative for hydatid cyst. Fiberoptic bronchoscopy was normal; therefore, the patient underwent surgical operation. The pathology of the mass was primary pulmonary hemangiopericytoma
