General description

The claudins are a family of over twenty proteins which are components of tight junctions. Tight junctions are specialized regions of cell-to-cell contact made up of a network of strands to act as a molecular ‘gasket′ for preventing the leakage of ions, water, etc. between cells. They are abundant in luminal epithelial sheets where they maintain epithelial cell polarity. The claudins constitute a variable component, with specific claudins being associated with specific tissues. The immunoreactivity for anti-claudin 1 is membranous and is found in nearly all carcinomas. The staining is much stronger in the carcinoma cells than in normal tissues. Anti-claudin 1 in a panel of immunostains that includes antibodies against EMA (positive), S-100 (negative), and GLUT1 can be utilized as a robust marker in the diagnosis of perineurioma and neurofibroma. Some studies have shown anti-claudin 1 to be a specific marker for meningiomas. Therefore, anti-claudin 1 with anti-EMA, anti-S-100 protein, anti-CD34, and anti-glial fibrillary acidic protein (GFAP) may be helpful in the differentiation of meningiomas from histologic mimics.

Perineuriomas are uncommon benign peripheral nerve sheath tumors that include soft tissue, sclerosing, and intraneural variants. Fewer than 50 soft tissue perineuriomas have been reported to date, and the clinical significance of atypical histologic features is unknown. To characterize these

Perineuriomas are benign peripheral nerve sheath neoplasms composed of perineurial cells with characteristic immunohistochemical and ultrastructural features. They have been traditionally classified into two main types according to their location--intraneural and extraneural--and overlap histologically with many other tumors, which may
