Solitary fibrous tumor (SFT) is a mesenchymal neoplasm that appears primarily in the pleura and rarely in intrapulmonary or endobronchial topography. The authors report the case of a 47-year-old woman who presented obstructive respiratory symptoms for 4 years. The chest computed tomography and bronchoscopy showed an obstructive polypoid lesion located between the trachea and the left main bronchus associated with distal atelectasis of the left lung. A resection of the lesion was performed and, macroscopically, the mass was oval, encapsulated, and firm, measuring 2...

AIMS: The lung lesion (IgG4-L) of IgG4-related disease (IgG4-RD) is a condition that occurs together with IgG4-RD and often mimics the lung lesion (iMCD-L) of idiopathic multicentric Castleman's disease (iMCD). Because no clinical and pathological studies had previously compared features of these diseases, we undertook this comparison with clinical and histological data. METHODS AND RESULTS: Nine patients had IgG4-L (high levels of serum IgG4 and of IgG4(+) cells in lung specimens; typical extrapulmonary manifestations)...

Small (2 cm) peripheral lung lesions and ground glass opacities remain a difficult subset of lung lesions for the diagnosis and management of lung cancer. Surgical biopsy is more difficult for these lesions because intraoperative localization has to be made without the aid of direct visualization or manual palpation. Electromagnetic navigation bronchoscopy can be used in the operating room to identify a small peripheral lesion and marked using an injection of methylene blue, which can be seen on the visceral pleura of the lung...

Isolated pleural metastasis with pleural effusion is a rare occurrence in malignant melanoma. We report an unusual case of a patient with chronic lymphocytic leukemia (CLL) and recurrent pleural effusions. The pleural fluid cytology and immunohistochemistry profile were consistent with the diagnosis of CLL. However, chemotherapy with pentostatin, cyclophosphamide, and rituximab did not result in any meaningful clinical response. A video-assisted thoracoscopic surgery and biopsy of the affected nodular parietal layer of the pleura were consistent with malignant melanoma...

Malignant pleural mesothelioma (MPM) is a rare aggressive cancer of the pleura primarily associated with prior exposure to asbestos. The current standard of care for patients suffering from MPM is a combination of cisplatin and pemetrexed (or alternatively cisplatin and raltitrexed). Most patients, however, die within 24 months of diagnosis. New therapies are therefore urgently required for this disease. Inflammation is thought to be a key element in the pathogenesis of MPM, and recently Kdm6 family members (Kdm6a and Kdm6b) have been identified as playing important roles in inflammatory processes...

Vulvar tumors are not very common and account for about 4% of all cancers affecting the female genital organs. Frequently, malignant neoplasia of this site have squamous phenotype and the rare cases of metastasization are reported in the locoregional lymph nodes and in the surrounding organs. We report a case of metastasization of a vulvar squamous cell carcinoma in an unusual place such as the parietal pleura, in a relapsing patient that was submitted to a surgical vulvectomy the previous year.

Nanoparticles have been implicated in the development of pleural effusions in exposed factory workers while in experimental animal studies it has been shown that they induce inflammation, fibrosis and carcinogenesis in the pleura. The scope of this study was to investigate the direct effects of silver nanoparticles exposure on the membrane permeability of sheep parietal pleura, of primary sheep pleural cell monolayers and on a human mesothelial cell line. Our findings suggest that acute (30min) exposure increases the pleural permeability ex vivo, while longer (24h) exposure in vivo leads to late decrease of the pleural cell monolayers permeability...

A 152-week-old male Royal College of Surgeons (RCS) rat kept as a non-treated animal in a long-term animal study presented with a soft mass in the anterior mediastinum, which adhered to the pleura of the lung. Histopathologically, the mass mainly consisted of round to short spindle-shaped tumor cells that had infiltrated through the hyperplastic thymic tissue. The tumor cells were arranged in loose to dense sheets. Nuclei were moderate in size and round to spindle-shaped, with small nucleoli. Almost all tumor cells exhibited abundant eosinophilic cytoplasm, including eosinophilic granules of a range of sizes...

BACKGROUND: Intrathoracic herniation of gastric tube (IHGT) pull-up via the retrosternal route is a rare complication following esophagectomy, which is caused due to an injury in the parietal pleura during a blunt dissection of the retrosternal space. However, little is known regarding the clinical impact of IHGT pull-up via the retrosternal route. PATIENTS AND METHODS: Clinical data of 231 patients receiving gastric tube reconstruction via the retrosternal route following esophagectomy were collected from medical charts...

Endometriosis is a common gynecological disorder most often involving the pelvic region. Although it is rare, endometriosis occurring outside of the peritoneal cavity most commonly occurs within scars of the abdominal wall, but it has been reported in the lungs, pleura, kidneys, brain, and the extremities. Herein, we present 2 cases of endometriosis, including 1 case of endometriosis of the wrist that clinically mimicked a soft-tissue neoplasm and 1 case of right-groin endometriosis mimicking synovial sarcoma during the initial pathological interpretation of findings on fine needle aspiration...

Larvae of malacostracan crustaceans represent a large fraction of modern day zooplankton. Plankton is not only a major part of the modern marine ecosystem, but must have played an important role in the ecosystems of the past as well. Unfortunately, our knowledge about plankton composition of the past is still quite limited. As an important part of today's zooplankton, malacostracan larvae are still a rarity in the fossil record; many types of malacostracan larvae dominating the modern plankton have so far not been found as fossils...

INTRODUCTION: Arthroscopy has become a major diagnostic tool and treatment option for shoulder pathology. However rare, respiratory complications such as a pneumothorax have been reported in patients undergoing shoulder arthroscopy. Surgery - as well as anesthesiology-related factors and respiratory comorbidity have been hypothesized to intervene in the onset of respiratory complications. CASE REPORT: We report the case of a 42-year-old male patient who underwent an arthroscopy of the left shoulder...

BACKGROUND: The cell surface glycoprotein mesothelin is highly expressed in several malignant diseases. Normal mesothelin expression is limited to mesothelial cells lining the pleura, peritoneum, and pericardium, making it a biomarker and an attractive target for cancer therapy. METHODS: We investigated tumor mesothelin expression and serum mesothelin levels in patients with epithelial ovarian cancer or borderline tumors. In total, 161 patients selected from a previous prospective study were analyzed for tumor mesothelin expression using immunohistochemistry and serum mesothelin expression using enzyme-linked immunosorbent assay...

INTRODUCTION: Malignant pleural mesothelioma (MPM) is a rare fatal asbestos-related malignancy originating in the mesothelial cells of the pleura. A platinum-based doublet containing a third-generation antifolate is the front-line standard of care whilst there are no approved second-line treatments for MPM which remains a disease setting to test the efficacy of new therapeutic agents. METHODS: Bone marrow mesenchymal stromal cells (BM-MSCs) were loaded with pemetrexed (PMX) and paclitaxel (PTX) according to a standardized procedure...

Accurate assessment of the invasion of intrathoracic structures by stage III thymic tumors assists their appropriate management. The present study aimed to evaluate the efficacy of computed tomography (CT) features for the prediction of stage III thymoma invasion. The pre-operative CT images of 66 patients with confirmed stage III thymic tumors were reviewed retrospectively. The CT features of invasion into the mediastinal pleura, lungs, pericardium and great vessels were analyzed, and their sensitivity, specificity, positive predictive value (PPV), negative predictive value and accuracy were calculated...
