Usefulness of Claudin 4 in the cytological diagnosis of serosal effusions
…peritoneum (6), were found to be positive. Claudin 4 was also extremely useful in detecting single-tumor cells dispersed among heavy inflammatory reaction. Because of its high sensitivity (99.1%) and specificity (100%), Claudin 4 might…

Ultrastructural histochemistry of mesotheliomas and adenocarcinomas in malignant effusions
…along the outer surface of the cell aggregates, while carcinomas displayed a positive reaction either on the outer surface or on both inner and outer surfaces of the clusters. The diagnostic significance of the above-mentioned…

Tenascin expression and distribution in pleural inflammatory and fibrotic diseases
…as a marker of active pleural involvement. For this purpose we analyzed 71 histological samples of inflammatory and fibrotic pleura from patients with asbestos-induced pleural reaction (n = 6), postcardiac injury syndrome (n = 6…

Positive FDG-PET/CT of the pleura twenty years after talc pleurodesis: three cases of benign talcoma
…This inflammatory reaction could decrease with time, as in other inflammatory processes. Since talc is not metabolized by the body, the FDG-PET scan can remain positive, most likely because of a foreign-body granulomatous reaction…

Cytogenetic findings in an effusion secondary from pleural mesothelioma
…years earlier a similar episode had been diagnosed as tuberculous pleuritis. Routine examination of cells in the fluid showed only a nonspecific reaction of the lining cells, and a pleural biopsy found no signs of cancer…

Pleural granuloma mimicking malignancy 42 years after slurry talc injection for primary spontaneous pneumothorax
…malignant cells or asbestos fibers. Keyhole surgery was converted to open surgery and the pleura was removed. The pathologist diagnosed chronic granulomatous pleuritis caused by a foreign body reaction, likely talc. Only on detailed questioning did…

Chronic follicular pleuritis: a B cell-rich form of nonspecific pleuritis/fibrosis
…pleuritis/fibrosis (NSP) is rendered. The histology of this reaction has not been well described including a pattern of B cell lymphoid hyperplasia described as "chronic follicular pleuritis (CFP)". Thirty-two cases of NSP were studied…

Diseases associated with asbestos exposure. Diagnostic perspectives in forensic pathology
…and its numerous applications. Its biological effects, which include fibrogenesis and carcinogenesis, may be related to the cellular reaction, to its large specific surface, or to the size and shape of the fibers. Its oncogenic action…

Railroad workers with pleural plaques: II. Small airway dysfunction among asbestos-exposed workers
…groups the VTG:TLC ratio was elevated compared with controls. Increased VTG is a sign of small airways dysfunction. In asbestos-exposed subjects, it might be caused by an early peribronchial reaction to inhaled asbestos fibers.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue type arising in the pleura with pleural fibrous plaques in a lathe worker
…pleura and diffuse infiltration of small- to medium-sized B lymphocytes. Polymerase chain reaction-based analysis detected monoclonal rearrangement of immunoglobulin heavy-chain genes. Histologic diagnosis was extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue…

Additional proteins in BAL fluid of Metsovites environmentally exposed to asbestos: more evidence of "protection" against neoplasia?
…The two proteins were present in all Metsovites with PCs but in none without PCs and also in none of the control groups. This study further separates two groups of Metsovites with different reaction to asbestos…

Comparison of antibodies to HBME-1 and calretinin for the detection of mesothelial cells in effusion cytology
…identifying mesothelial cells in cytologic samples, showing the highest sensitivity for mesothelial cells, as evidenced by a more intense staining reaction in a higher percentage of cells than with HBME-1. Published 2001 Wiley-Liss, Inc.

Radiological features of asbestos-related visceral pleural changes
…Generally, visceral pleural reactions follow the mesothelial cells response to various injurious substances, including asbestos, and even saline. The changes are nonspecific. They may occur subsequent to pleural reactions associated with many conditions, which include tuberculosis…

Pleural disease during treatment with bromocriptine in patients previously exposed to asbestos
Bromocriptine, which is used in the treatment of Parkinson's disease, can cause adverse pleuropulmonary reactions. Exposure to asbestos can result in similar lesions. Fifteen patients with former exposure to asbestos, who developed pleural fibrosis after…
