Pulmonary acantholytic squamous cell carcinoma mimicking lepidic pattern adenocarcinoma

Abstract

Dear Editor, An 84-year-old male patient with a history of smoking and recent pneumonia symptoms of fever, difficulty in breathing, and weakness presented to the chest disease clinic. The patient had a left-sided suspicious lung mass on his chest X-Ray (CXR). Written informed consent was obtained from the patient. Chest computed tomography (CT) revealed a mass of 3x2 cm on the superior lobe of the left lung (Figure 1). CT-guided transthoracic tru-cut biopsy of the chest was performed.
