A 60-year-old male smoker was admitted with the chief complaints of cough, dyspnea and loss of appetite and weight. Skiagram chest revealed a left hilar shadow and a band of hyperlucency outlining the arch of aorta [Figure 1]. The left lung volume was reduced. Higher imaging in the form of contrast-enhanced computed tomography (CECT) of the chest showed collapse of the left upper lobe with abrupt ending of the left upper lobe bronchus [Figure 2]. Flexible bronchoscopy revealed left upper lobe growth, which on histopathologic examination of the biopsy specimen proved to be small cell carcinoma.
