This case is about a 70-year-old man who presented with symptoms and laboratory reports that indicated differentials toward an infectious disease (pneumonia and tuberculosis). A lung mass was found in his chest X-ray and in the computerized tomography (CT) scan of his thorax. A biopsy was taken from the lung mass, and histopathological examination and immunohistochemical staining of the biopsy were done. The results revealed the presence of spindle cell carcinoma (SpCC) with vimentin and cytokeratin positivity. Spindle cell lung cancer is a rare type of non-small cell lung carcinoma, for which all available research indicates a poor prognosis. Due to the rarity of diagnosis, there is a dearth of information about the epidemiology and overall survival of affected patients., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Samanta et al.)

Emphysema is a progressive and degenerative lung disease that most commonly occurs due to many years of smoking or exposure to smoke and irritants. It is also seen in the congenital absence of the alpha-1-antitrypsin enzyme. Bullous emphysema is an advanced stage of the disease where strictures of the bronchi permit the inspired air to enter the bronchi but close on expiration, causing air retention and alveolar dilation, destruction, and atrophy. Multiple small bullae coalesce to form a giant bulla (defined as occupying more than one-third of the hemithorax), which causes respiratory symptoms and mediastinal shifting and leads to a poor general condition of the patient. Here, we present the cases of two patients diagnosed with bullous emphysema who presented within three months of each other. This article details the similarities and differences in the approach to both cases and the learning experience from these presentations, especially in acute symptomatology. Bullous emphysema is usually confused with a pneumothorax on a simple chest X-ray; hence, it is imperative to look for the lung margins and confirm the diagnosis using computed tomography of the thorax., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Samanta et al.)
