Within 35 years 1008 patients were treated that were taken ill in a malignant tumor of face, jaw and mouth. There was found in five patients a distant metastasis of a carcinoma in lower yaw. One case with metastasis in left mandibular condyle is being described. The diagnosis was found by using conventional X-ray examination, Computertomography and aspiration cytology.

Background: Pulmonary bronchial leiomyosarcoma is an extremely rare malignant tumour of the lung originating from the mesenchymal tissue. The retroperitoneal region is the most common site of leiomyosarcoma. It exhibits a high degree of malignancy and a poor prognosis, thereby highlighting the significance of early diagnosis of this disease.

Introduction: Endobronchial metastases (EBMs) are rare, with primary tumours predominantly of breast, renal, and colorectal origin. Bronchoscopy is the diagnostic gold standard, with histological confirmation through immunohistochemical study.
Cases: We presented three cases of EBMs, one secondary to colorectal cancer and two associated with renal tumours.

Objective: Epithelial-mesenchymal transition (EMT) and metastasis are the primary causes of mortality in non-small-cell lung cancer (NSCLC). 5'-3' exoribonuclease 2 (XRN2) plays an important role in the process of tumor EMT. Thus, this investigation mainly aimed to clarify the precise molecular pathways through which XRN2 contributes to EMT and metastasis in NSCLC.

Tracheal obstruction can arise from multiple conditions, including chronic obstructive pulmonary disease, asthma, foreign bodies, tumors, and acute heart failure. We report a case of a 43-year-old man with cervical liposarcoma who, following surgical excision, chemotherapy, and radiation, presented with severe dyspnea and was admitted to our hospital. A CT scan detected an endotracheal mass causing significant obstruction, suspected to be malignant.

A man in his 60s, who had undergone surgery for rectal cancer, liver metastases, and lung metastasis, had a past history of myocardial infarction and ventricular fibrillation with reduced cardiac functions. He was referred to our department because of a pulmonary nodule shadow in the S2 right upper lobe and a bronchial cast shadow along the B2 bronchus. Robot-assisted thoracoscopic right S2 segmentectomy was performed and intraoperative bronchoscopy revealed a polyp-like tumor within B2a.
