Lung cancer is the most common cancer in the world. Despite this, there have been few cases of simultaneous primary and metastatic cancers in the lung reported, let alone coexisting with tumor-to-tumor metastasis. Herein, we describe an extremely unusual case. A 61-year-old man with a history of colon adenocarcinoma was revealed as having three nodules in the lung 11 months after colectomy. The...

BACKGROUND Thoracoabdominal actinomycosis is rare, especially in the context of readily available medical facilities. METHODS Case report and review of the literature. CASE REPORT A 54-year-old male patient was admitted because of hemoptysis and a pulmonary infiltrate in the left lower lobe. His history was unremarkable except for chronic gastritis and an elective laparoscopic cholecystecto...

A patient is described who presented with left upper lobe collapse due to endobronchial metastatic prostate carcinoma. Treatment with the oral antiandrogen cyproterone acetate resulted in resolution of the occluding endobronchial carcinoma and lobar re-expansion.

An extremely rare case of stromal micropapillary predominant lung adenocarcinoma is presented in this study. A 70-year-old woman visited our hospital because of an abnormal shadow on chest X-ray. Chest computed tomography revealed a nodule in the left lower lobe and a mass in the left upper lobe. She underwent an exploratory thoracotomy owing to the suspicion of advanced lung cancer. Pathologic...

A 38-year-old man without any symptoms was admitted to our institution because of an abnormal shadow found incidentally on a chest X-ray. Chest computed tomography showed a round mass in the lingular segment of the left upper lobe. Lingular segmentectomy was performed, and the histopathological diagnosis was intrapulmonary schwannoma. Immunohistochemical staining revealed a positive result for ...

A 56-year-old diabetic man presented with left upper lobe collapse and postobstructive pneumonitis. Fiberoptic bronchoscopy revealed an endobronchial mass obstructing the left mainstem bronchus. The lesion resembled a bronchial adenoma; however, cytologic and histologic examination revealed invasive mucormycosis. The patient was treated with intravenous amphotericin B followed by endoscopic las...

BACKGROUND Kartagener syndrome (KS) is a rare disorder characterized by the triad of chronic sinusitis, bronchiectasis, and situs inversus. CASE PRESENTATION A 23-year-old man was admitted to our hospital because of recurrent cough with purulent expectoration, which had occurred intermittently for the past ten years. During the past 3 years, the episode frequency was 3-4 times per year. He wa...

Following left upper lobectomy for a pulmonary nodule, complete 180-degree torsion of the left lower lobe with haemorrhagic infarction occurred. Despite re-exploration within 24 hours of the initial procedure the patient died. Postoperative torsion requires early diagnosis and resection of the gangrenous tissue.
