RESUMO
We report the case of a 37-year-old woman who presented with severe persistent "asthma" requiring repeated courses of steroids and bronchodilators. Spirometry was suggestive of upper airway obstruction. Computerized tomography scan [CT] demonstrated a polypoid mass in the cervical trachea obstructing 90% of the lumen. Urgent tracheostomy was performed followed by bronchscopic excision of the mass. Histopathological diagnosis of schwannoma was confirmed using immunohistochemical markers. We found only 20 primary tracheal schwannoma cases previously reported in the English literature

A 46-year-old female presented with a 20-day history of right pleuritic chest pain and progressive shortness of breath. She was found to have a right pleural based malignancy initially thought to be a malignant mesothelioma but staining with the mesothelioma tumor markers calretinin, HBME-1 and CK5/6, was negative. Some epitheial markers were positive and microscopically it was consistent with a poorly differentiated large-cell carcinoma. The case was diagnosed as a pseudomesotheliomatous lung carcinoma of poorly differentiated large-cell type
