BAP1 Immunohistochemistry and p16 FISH in the Diagnosis of Sarcomatous and Desmoplastic Mesotheliomas
…help diagnose sarcomatous and desmoplastic mesotheliomas. These tumors can be hard to distinguish from organizing pleuritis, a benign reaction of the pleura. The authors tested tissue from 20 such pleural mesotheliomas, from 18 men and 2…

Malignant mesothelioma and CEA staining
…which is neither tumor- nor organ-specific. The author added that CEA staining results are not valid unless this reaction is first removed by absorbing the antisera with NCA. Earlier reports describing CEA in mesothelioma had…

Diffuse intrapulmonary malignant mesothelioma masquerading as interstitial lung disease: a distinctive variant of mesothelioma
…micropapillary, and solid patterns. Initial diagnoses by referring pathologists included reactive changes (1), hypersensitivity pneumonitis versus drug reaction (1), desquamative interstitial pneumonia versus neoplasm (1), and mesothelioma (2). Microscopic pleural involvement was identified in 4 cases…

Epithelial mesothelioma with deciduoid features: report of four cases
Deciduoid mesothelioma is the designation given to an unusual morphologic variant of epithelial mesothelioma that closely simulates exuberant ectopic decidual reaction. Because all four previously reported cases involved the peritoneum and occurred in young women without…

Nuclear Brachyury Expression Is Consistent in Chordoma, Common in Germ Cell Tumors and Small Cell Carcinomas, and Rare in Other Carcinomas and Sarcomas: An Immunohistochemical Study of 5229 Cases
…chordoma, whereas others have concluded that brachyury is expressed in many types of common carcinomas by reverse transcription polymerase chain reaction and immunohistochemistry and could be involved in the epithelial-mesenchymal transition and metastatic process. In…

Identification of DAB2 and Intelectin-1 as Novel Positive Immunohistochemical Markers of Epithelioid Mesothelioma by Transcriptome Microarray Analysis for Its Differentiation From Pulmonary Adenocarcinoma
…adenocarcinoma. The increased mRNA expression of DAB2 and Intelectin-1 was validated by reverse transcriptase polymerase chain reaction of RNA from tumor tissue and protein expression was validated by Western blotting of 5 mesothelioma cell lines…

Immunohistochemical staining for vimentin and keratin in malignant mesothelioma
…were negative. In the mesotheliomas that did stain, both epithelial and spindled elements gave a positive reaction. Three alcohol-fixed lung cancers and two blocks of alcohol-fixed pleura failed to stain for vimentin. By contrast…

A novel biotinylated probe specific for hyaluronate. Its diagnostic value in diffuse malignant mesothelioma
…staining for hyaluronate. Furthermore, the staining reaction was classed as moderate or greater in 26 mesotheliomas (79%), thus suggesting the utility of this probe in the differential diagnosis of malignant mesothelioma versus adenocarcinoma. We conclude that…

Leu-M1 antigen in human neoplasms. An immunohistologic study of 400 cases
…included 113 of 199 carcinomas, most of them (58%) adenocarcinomas. Only one of 34 sarcomas showed a focal positive reaction. Leu-M1-related antigen was not detected in any of 18 mesotheliomas, 15 germ cell tumors…

Utility of BAP1 Immunohistochemistry and p16 (CDKN2A) FISH in the Diagnosis of Malignant Mesothelioma in Effusion Cytology Specimens
…might also be useful in effusion cytology specimens, we examined 15 biopsies of epithelial mesotheliomas and 3 benign mesothelial reactions and corresponding effusion cytology paraffin-embedded cell blocks. Four cytology specimens were too scanty for p16…
