BACKGROUND: Homozygous deletion of 9p21 detected by fluorescence in situ hybridization (FISH) and loss of BRCA1-associated protein 1 (BAP1) expression detected by immunohistochemistry (IHC) are useful for the differentiation between malignant pleural mesothelioma (MPM) and reactive mesothelial hyperplasia. The authors previously described that IHC expression of the protein product of the methylthioadenosine phosphorylase (MTAP) gene, which is localized in the 9p21 chromosomal region, was correlated with the deletion status of 9p21 FISH in MPM tissues...

PURPOSE: Pleural effusion, an accumulation of fluid in the pleural space, usually occurs in patients when the rate of fluid formation exceeds the rate of fluid removal. The differential diagnosis of tuberculous pleurisy and malignant pleural effusion is a difficult task in high tuberculous prevalence areas. The aim of the present study was to identify novel biomarkers for the diagnosis of pleural fluid using proteomics technology. MATERIALS AND METHODS: We used samples from five patients with transudative pleural effusions for internal standard, five patients with tuberculous pleurisy, and the same numbers of patients having malignant effusions were enrolled in the study...

During the course of disease, many cancer patients eventually present with metastatic disease including peritoneal or pleural spread. In this context, cytology specimens derived from ascites or pleural effusion may help to differentiate malignant from benign conditions and sometimes yield diagnosis of a malignancy. However, even when supported by immunohistochemistry, cytological interpretation can be challenging, especially if tumor cellularity is low. Here, we investigated whether targeted deep sequencing of formalin-fixed and paraffin embedded (FFPE) cytology specimens of cancer patients is feasible, and has diagnostic and clinical impact...

BACKGROUND: With advent of personalized medicine, precise classification of malignant tumors becomes essential. Squamous cell carcinoma (SCC) is rarely found in serous effusions and has morphologic and immunohistochemical (IHC) overlap with other neoplasms. METHODS: 17-year review identified 49 fluids from 26 patients where SCC was recognized. RESULTS: SCC was more frequent in pleural fluid (84%) and rare in other effusions. Lung SCC was common (65%), followed by head and neck (16%), with other origins less represented...

BACKGROUND AND OBJECTIVE: Pleuroscopy is the test of choice for patients with suspected malignant pleural effusion and negative cytology. Biopsies negative for malignancy are frequently attributed to non-specific pleuritis, which poses a dilemma in patients with a known active malignancy, raising concern for a false-negative result. Our primary objective was to determine the outcomes of patients with active malignancy who had a non-malignant diagnosis on pleuroscopy. METHODS: Retrospective review of all pleuroscopy cases from January 2005 to January 2015 at our institution was conducted...

Lenvatinib, a novel potent multikinase inhibitor, was approved for the treatment of radioiodine-refractory differentiated thyroid cancer based on results from phase III trial (SELECT study). Thyroid cancer is a diverse disease that includes anaplastic thyroid cancer (ATC), which the most aggressive form of the disease, although it accounts for <2% of all thyroid cancers. Current treatments for ATC have limited efficacy. We report the case of a woman with recurrent well-differentiated papillary carcinoma of the thyroid that had transformed into ATC who developed a perforation of the small intestine secondary to a marked effect of lenvatinib...

Kaposi's sarcoma-associated herpesvirus (KSHV) is associated with the human malignancy Kaposi's sarcoma and the lymphoproliferative disorders primary effusion lymphoma and multicentric Castleman's disease. KSHV establishes lytic infection of monocytes in vivo, which may represent an important cellular reservoir during KS disease progression. KS tumors consist of latently infected endothelial cells; however, lytic phase gene products are important for KS onset. Early KS lesion progression is driven by proinflammatory cytokines supplied by immune cell infiltrates including T cells and monocytes...

BACKGROUND: The important diagnostic challenge facing the cytopathologist is whether a mesothelial proliferation on effusions represents a malignant mesothelioma (MM) or a benign mesothelial hyperplasia (MH). Here, we evaluated the diagnostic utility of BAP1 immunohistochemistry (IHC) in distinguishing between reactive and neoplastic mesothelial cells. METHODS: In pleural and peritoneal effusions from 147 patients with diagnosed MM or with a differential diagnosis of MM and MH, the expression of BAP1 was examined by IHC on paraffin-embedded cell blocks (n = 121) and biopsies (n = 44)...

Chylothorax is an unusual cause of pleural effusion, typically caused by trauma or malignancy. Waldenstrom's macroglobulinaemia (WM) is a clinicopathological entity demonstrating lymphoplasmacytic lymphoma in the bone marrow with an IgM monoclonal gammopathy in the blood. Recurrent chylous effusions are often resistant to conservative treatment and may require surgical intervention. We present a unique case of a 50-year-old woman with recurrent chylothorax secondary to WM that completely resolved with ibrutinib therapy...

Primary Intestinal Lymphangiectasia (PIL) is a rare disease of unknown aetiology which presents in the paediatric age group with anasarca, diarrhoea, hypoproteinaemia, lymphoedema and chylous effusions. Tuberculosis, filariasis, chest trauma, malignancies and haematological disorders usually contribute to most cases of secondary lymphangiectasia and chylous effusions. We hereby describe a case of PIL presenting with chylous effusions which remained undiagnosed for eight years.

Metformin, the most used drug for the treatment of diabetes type 2 patients, has been shown to have anti-cancer properties. In this study, we found that metformin induced apoptosis in Primary Effusion Lymphoma (PEL) cells, an aggressive B cell lymphoma associated with KSHV against which the conventional therapies usually fail. The cytotoxic effect of metformin correlated with intracellular reactive oxygen species reduction, activation of AMPK, the inhibition of pro-survival pathways such as mTOR and STAT3 and the down-regulation of v-FLIP, a latent viral antigen that also plays a pivotal role in PEL cell survival...

Papillary thyroid carcinoma (PTC) is by far the most common thyroid malignancy (over 85%) of all the thyroid cancers. It has excellent prognosis and 10-year survival rate in most of the cases (95%). Most of the tumors are indolent and do not recur or metastasize after removal. However, widespread metastases to lung, skeleton, central nervous system and, occasionally, other organs may be observed. In rare instances, this disease may metastasize to the pleura and manifest as a malignant pleural effusion (MPE) and portend poor prognosis...

Primary pericardial malignant mesothelioma (PPM) is a very rare malignancy, with an incidence of less than 0.002% and represents less than 5% of all mesotheliomas. The cause of pericardial mesothelioma is uncertain that differ from pleural mesothelioma which is associated with asbestos exposure. This malignancy is terribly aggressive and has very poor prognosis with less than six months of overall survival. We present a case of a 71-year-old woman who was diagnosed with cardiac tamponade caused by PPM and received chemotherapy with pemetrexed and cisplatin for six months...

INTRODUCTION: Although pleural effusion (PE) can be caused by several pathologies like congestive heart failure, infections, malignancies, and pulmonary embolism, it is also a common finding in chronic kidney disease (CKD). Diagnostic thoracentesis is of limited value in the differential diagnosis, and the role of more invasive investigations like medical thoracoscopy (MT) is still unclear. AIM: To evaluate the usefulness of MT in unexplained PE in CKD. MATERIALS AND METHODS: In the electronic database of our Institution, we retrospectively searched for patients with CKD who underwent MT for unexplained PE between January 2008 and August 2016...
