General description
Caveolin-1 (CAV-1) is a cell membrane-associated structural component of flask-shaped plasma membrane invaginations termed caveolae. CAV-1 is expressed at different levels in different tissues, with the highest in adipocytes, endothelial cells, fibroblasts, and mesothelial cells. Anti-CAV-1 is useful in assisting in the identification of epithelioid mesothelioma. A study by Amatya et al. indicates CAV-1 expression in all 80 (100%) epithelioid mesotheliomas, whereas only 6/80 (7.5%) of the lung adenocarcinomas were positive for CAV-1. Staining in most mesotheliomas was strong and diffuse when compared with the weak, focal staining (no more than 1% of the tumor cells) seen in the lung adenocarcinomas, anti-CAV-1 is considered a very useful marker for assisting in discriminating between these two malignancies. They also indicated that anti-CAV-1 is comparable to other mesothelioma markers such as anti-calretinin and anti-D2-40 (podoplanin) that are commonly used to assist in the differentiation between epithelioid mesotheliomas and lung adenocarcinomas. Anti-CAV-1 is also useful in identification of Ewing sarcoma/PNET. Literature indicates CAV-1 expression in 368 (96%) of 383 cases of Ewing sarcoma/PNET. In summary, anti-CAV-1 is very useful in the differentiation of epithelioid mesothelioma from lung adenocarcinoma and identification of Ewing sarcoma/PNET.

Although they were discovered more than 50 years ago, caveolae have remained enigmatic plasmalemmal organelles. With their characteristic "flasklike" shape and virtually ubiquitous tissue distribution, these interesting structures have been implicated in a wide range of cellular functions. Similar to

Ewing's sarcoma (ES)/peripheral neuroectodermal tumor (PNET) are malignant neoplasms affecting children and young adults. We performed a study to typify the histological diversity and evaluate antibodies that may offer diagnostic/prognostic support. In total, 415 cases of genetically confirmed paraffin-embedded ES/PNET

The incidence of mesothelioma is increasing in Europe, Japan and other developing countries. There is difficulty in the accurate diagnosis of mesothelioma and its differentiation from lung adenocarcinoma. Mesothelioma shows a complex immunohistochemical profile. Therefore, the use of a immunohistochemical
