Giant intrapulmonary solitary fibrous tumor with signs of malignancy.

Solitary fibrous tumor (SFT) is an extremely rare mesenchymal neoplasm usually detected in the pleura, which generally follows a benign course. The localization inside lung parenchyma has more rarely been reported. We present a case of a 51-year-old male with a dry cough, dyspnea, chest pain, and increased perspiration. Radiological images revealed a giant circumscribed mass on the right side of the chest. A transbronchial cryobiopsy of the lung was performed and revealed an SFT. The right upper lobectomy through lateral thoracotomy was performed. The pathological examination confirmed an SFT with a central zone of necrosis that is a sign of malignancy. At a 2-year follow-up, the patient is free of symptoms and with no evidence of recurrence. Although the intrapulmonary localization of an SFT is a rare entity, we should be aware of it as a potential malignant pulmonary neoplasm.

Think outside the coronary artery: Extremely rare case of STEMI in young man.

Acute myocardial infarction caused by a bronchogenic cyst is a very rare pathology. It occurs as a result of external compression of the coronary artery by the cyst, leading to myocardial ischemia. The present case illustrates that a bronchogenic cyst, which is generally considered to be a chronic disease entity with gradual onset of symptoms, can manifest acutely as a life-threatening condition. Timely invasive coronary intervention is critical in the acute management of this complication while multimodality imaging assessment is essential in the subsequent management of the underlying etiology.

Primary Pulmonary Meningioma With Rhabdoid Features.

Only 1% to 2% of meningiomas have primary extrameningeal location, which is mostly head and neck region. Primary pulmonary meningiomas (PPMs) are even more uncommon with up to 50 cases reported in the literature. Only 5 cases of PPM with confirmed or possible malignancy have been previously described. Three-grade classification of meningiomas with the accordingly growing risk of aggressive behavior of the tumor has been proposed by the World Health Organization. As it is based on correlations between morphological and clinical features of intracranial meningiomas, the analogous prediction of ectopic tumors prognosis remains questionable due to scarce number of cases. In this article, we present a rare case of PPM with rhabdoid features (World Health Organization grade III), which lacked other signs of malignancy. The patient is doing well for 2 years after the thoracoscopic wedge resection without evidence of the disease recurrence.

Preoperative predictors of conversion in thoracoscopic surgery for pleural empyema.

OBJECTIVES: Thoracoscopy is an effective treatment method for pleural empyema; however, it is still not well defined as to which patient subgroups could benefit from it the most. The aim of the study was to identify preoperative factors that could facilitate selecting appropriate surgical intervention and to evaluate early postoperative period. METHODS: Seventy-one patients were prospectively included in the study, which was conducted from January 2011 to June 2014. Thoracoscopic surgery for Stage II/III pleural empyema was performed in all patients. Thoracoscopy failed in 18 (25.4%) patients, requiring conversion to thoracotomy. The preoperative factors that could possibly predict conversion were analysed. RESULTS: Obliterated pleural space (12 patients) and failure to achieve lung re-expansion (6 patients) were the main reasons for conversion. Multivariable logistic regression analysis demonstrated that each day of illness [odds ratio 1.1 (95% confidence interval 1.0-1.2], P = 0.004] and frank pus [odds ratio 4.4 (95% confidence interval 1.2-15.3), P = 0.021] were independent predictors of conversion. Using receiver-operating characteristic analysis, it was determined that the duration of illness had a high predictive value for conversion [area under the curve 0.8 (95% confidence interval 0.7-0.9), P < 0.001]. The cut-off value for duration of illness was 16 days (sensitivity 94.4%, specificity 54.7%). The conversion group had a significantly greater need for postoperative intensive care unit stay ( P = 0.022) but a lower rate of reoperations ( P = 0.105). CONCLUSIONS: Duration of illness and frank pus discovered during thoracocentesis can help in selecting the patient for appropriate intervention. Earlier surgery for pleural empyema can reduce the rate of conversion and reoperation.
