Primary Leiomyosarcoma of the Bronchus: 18F-FDG PET/CT Findings

Primary leiomyosarcoma of the bronchus is an extremely rare malignant neoplasm. A 29-year-old man presented with persisting cough and sputum over 1 month. Unenhanced and contrast-enhanced chest CT showed a nodular lesion in the main bronchus of the left lower lobe and multiple enlarged lymph nodes in the mediastinum. Preoperative staging 18F-FDG PET/CT scan displayed a hypermetabolic lesion of the known nodule and mild FDG uptake of mediastinal lymph nodes. The histological examination confirmed bronchial leiomyosarcoma and reactive hyperplasia in lymph nodes.

In this study, Fe3O4 magnetic nanoparticles were synthesized in situ in the polyacrylamide/chitosan (PAAm/CS) hydrogel networks. The obtained hydrogels are characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD), and Raman spectroscopy. The results confirm that the three-dimensional network structure of the hydrogels is incorporated with Fe3O4 nanoparticles. The adsorption properties of PAAm/CS/Fe3O4 hydrogels for methylene blue (MB) in aqueous solution were studied using Ultraviolet and visible spectrophotometry (UV-Vis). The results show that when compared to P...

The results of Raman and FTIR spectra indicated successful electropolymerisation of PEDOT. The morphologies of PEDOT coating electrodes under different precursor solution concentrations and electrochemical polymerisation time were compared using field emission ...

In this study, a new MoAlB/Al composites with interface modification by in situ formed Al12Mo were prepared from MoAlB and Al powders for the first time. The thermal stability of MoAlB in MoAlB–Al system was investigated by differential scanning calorimetry and thermogravimetry analysis. It was found that the MoAlB can react with Al to form Al12Mo and a small quantity of AlB2 and MoB2. The formed Al12Mo can suppress the Al atoms diffusion and thus to hinder the reaction progress. The modified interfacial bond by in situ formed Al12Mo effectively improved the mechanical properties of the MoAlB/Al composites. The Vicke...

We report a case of a 44-year-old man with a localized right renal pelvis mass treated with a right nephroureterectomy. The pathological examination showed a high-grade urothelial carcinoma of the renal pelvis, stage III (pT3aNxM0). A few days later, he developed lower back pain, hematuria, cough with hemoptoic sputum and progressive dyspnea. Radiological explorations showed multiple bilateral lung nodules and a retroperitoneal mass. A CT-guided biopsy of the retroperitoneal mass revealed a high-grade angiosarcoma. A review of the nephrectomy specimen showed a microscopic focus of angiosarcoma in the urothelial carcinoma. ...

Abstract Primary pulmonary leiomyosarcomas are rare and diagnostically challenging group of neoplasms approximately constituting 0.2-0.5% of all primary lung malignancies. They originate from the smooth muscle cells of the bronchial wall, blood vessels or from the pulmonary interstitium. Here we present a case of 45 year old male with history of chronic cough, breathlessness and chest pain for few months. Clinical and radiological workup showed a left upper lobe lung mass. Endobronchial ultrasound guided (EUS) needle biopsy of the mass on histopathology confirmed leiomyosarcoma. Further through evaluation ruled ou...

These tumors are very rare. The most common clinical manifestation of pulmonary artery tumor is dyspnea followed by chest pain, cough, and haemoptysis. A case of 44-year-old male with history of progressive dyspnea, fever, cough, and weight lost...
