Аннотация
We report the case of a 69-year-old male patient with pulmonary sarcomatoid carcinoma (PSC). He presented to our hospital with fatigue and anorexia. Enhanced chest computed tomography revealed a mass with smooth margins and no contrast enhancement within, only observed around it in the right lower lobe. Initially, a lung abscess was suspected, and antibiotics were administered for two weeks. Nevertheless, fever, imaging findings, and blood tests showed no improvement. Considering the possibility of a malignant tumor, the patient underwent a right lower lobectomy. The histopathological diagnosis was sarcomatoid carcinoma. PSC is very rare and was difficult to distinguish from a lung abscess in this case. Herein, we discuss the progress and histopathology of this case in detail.
