title: Lung abscess mimicking lung cancer developed around staples in a patient with permanent tracheostoma.
abstract: A 68-year-old male with a tracheostoma due to hypopharyngeal cancer was admitted because his chest computed tomography (CT) showed a small nodule in the right middle lobe. Following a partial resection of the right middle lobe, histopathological diagnosis of the resected sample was that of organizing pneumonia. Eleven months later, chest CT showed a mass with pleural indentation and spiculation in the right middle lobe. 18-Fluorodeoxyglucose-positron emission tomography showed significant accumulation in the middle lobe tumor mass shadow. The abnormal chest shadow that had developed around surgical staples suggested inadequate resection and tumor recurrence. As the abnormal radiological shadow was enlarging, middle lobectomy was carried out. Histological examination revealed that the tumor was a lung abscess without malignant features. This is a unique case of lung abscess mimicking lung cancer which developed around staples used during partial resection of the lung.
