چکیده
TOPIC: Disorders of the Pleura TYPE: Medical Student/Resident Case Reports INTRODUCTION: Trapped lung is an uncommon complication malignant pleural effusion (MPE). It presents as post-thoracentesis hydropneumothorax (known pneumothorax ex vacuo, PEV) or that cannot be completely drained due to development chest pain [1]. important recognize PEV, although it may appear alarming, asymptomatic process not amenable tube placement. CASE PRESENTATION: 60 year old male with squamous cell carcinoma (SCC) buccal mucosa for which he underwent surgery radiotherapy 2 years ago, presented 1 week dyspnea. Chest X-ray showed a large right-sided ipsilateral displacement mediastinum [Figure 1]. He thoracentesis but procedure was terminated prematurely pain. Post-thoracentesis CT 2] evaluate underlying pathology thickening. Fluid cytology positive cells. subsequently thoracoscopy showing extensive involvement visceral and parietal surfaces appearing lesions. Pleural biopsies, done obtain more tissue next generation sequencing, were consistent An indwelling catheter placed at end long term management his effusion. Post-procedure partially expanded right PEV 3]. The patient this point good oxygenation on room air. manometry performed using digital manometer negative pressure. DISCUSSION: relatively rare site metastases from head neck SCC [2]. can develop adhesions pleura lesions [3]. Diagnosis should suspected when x-ray shows shift seen in our patient. patients also have drainage Effective trapped MPEs remains challenging. Various treatment modalities exist, including minimally invasive procedures such thoracocentesis catheters, well pleuroperitoneal shunt, thoracotomy, decortication. optimal approach balance therapeutic benefit versus required period convalescence disease poor life expectancy [4]. CONCLUSIONS: We present (PEV lung) (pleural cancer). In cases after drainage, consider will direct approaches. REFERENCE #1: Huggins JT, Doelken P, Sahn SA. unexpandable lung.

متن کاملSquamous cell carcinoma of lung with unusual site of metastasis
Background: Lung cancer ranks among the most common and most lethal malignancies worldwide. Once vascular or lymphatic invasions occur, metastatic dissemination to distant sites is common. Bone, liver, adrenals, and brain are the most frequent sites of the distant disease. In this study we present a case of squamous cell carcinoma of lung with metastasis of the left knee bursa.Case presentation...
متن کاملVX2-induced rabbit buccal carcinoma: a potential cancer model for human buccal mucosa squamous cell carcinoma.
The buccal mucosa is the site at highest risk of contracting malignancy in habitual betel-quid chewers who expose the buccal mucosa to high doses of carcinogens. Of all oral squamous cell carcinomas (SCCs), those of the buccal mucosa are most associated with the poorest prognoses. Therefore, an animal model would be helpful to evaluate new treatment modalities for buccal SCC. We evaluated wheth...
متن کاملRare case of squamous cell carcinoma of buccal mucosa metastasizing to interventricular septum in a young adult detected by 18F-FDG PET-CT
Metastatic tumors to the heart unlike primary cardiac tumors are not rare. Despite its frequency, cardiac metastasis is commonly detected only during autopsy as the symptoms of disseminated metastasis prevail over symptoms caused by cardiac metastasis and hence is overlooked most of the time. Tumors more commonly found metastasizing to the heart are malignancies of lung, breast, esophagus, lymp...
