Estenosis subglótica y granulomatosis con poliangeítis (Wegener) en dos casos: Report of two cases / Subglottic tracheal stenosis in Wegener disease

Granulomatosis with polyangiitis (GPA) or Wegener's disease is characterized by a granulomatous vasculitis of the upper and lower airways and kidney. It involves the lower respiratory tract causing subglottic tracheal stenosis, which occurs in approximately 22% of patients. We report two females aged 40 and 52 years, admitted to the hospital with a subglottic tracheal stenosis. Their symptoms and management are reviewed. The frst patient responded to rituximab. The second patient required a tracheostomy.

Embolismo pulmonar tumoral: Reporte de dos casos / Pulmonary tumor embolism: Report of two cases

Dyspnea and hypoxemia in a patient with cancer may have several causes, including infections, thromboembolism, metastases, and pulmonary injuries by drugs. We report a 47-year-old female with breast cancer and a 70-year-old male with urinary bladder cancer who were admitted for dyspnea, hypoxemia and pulmonary hypertension. Chest X rays and CT scans were normal. The ventilation-perfusion scintigram was highly suspicions of thromboembolism in the female. The male died 16 hours after admission and the post mortem examination revealed the presence of tumor cells in the pulmonary vasculature.
