Endobronchial epithelial-myoepithelial carcinoma of the lung.

Kim CH, et al. Thorax 2017;0:1–2. doi:10.1136/thoraxjnl-2017-211155 An 83-year-old woman presented to our emergency department with mild dyspnoea. The patient had been in her usual state of health until 3 days prior to admission. Her medical history revealed no specific illness, and she was a never-smoker. The patient’s vital signs were within normal range, and physical examination revealed decreased breath sounds in the right lower lung field. Arterial blood gas analysis showed an oxygen saturation of 97%, a partial oxygen pressure of 11.7 kPa and a partial carbon dioxide pressure of 4.9 kPa. Laboratory tests demonstrated a leucocyte count of 1.5x10/L, 76.8% of which were neutrophils, an erythrocyte sedimentation rate of 53 mm/hour and a high-sensitivity C-reactive protein level of 150.87 mg/L, suggesting the presence of an underlying inflammatory reaction. Laboratory examinations, including chemistry panels, were otherwise normal. A chest X-ray showed highly increased density in the right lung field (figure 1A, B). Chest CT displayed an 8.3×7.1 mm endobronchial mass
