Immunohistochemical Demonstration of EMA/Glut1-Positive Perineurial Cells and CD34-Positive Fibroblastic Cells in Peripheral Nerve Sheath Tumors

Intrathoracic Malignant Peripheral Nerve Sheath Tumor: Histopathological and Immunohistochemical Features

Malignant peripheral nerve sheath tumor (MPNST) is a rare nerve sheath tumor derived from Schwann cells or pleuripotent cells of neural crest. Neurogenic tumors make about 10-20% of all mediastinal tumors. Incidence of MPNST is 0.001% in general population and 0.16% in patients with neurofibromatosis I (NF I). We report a case of 60 year female presenting with progressive cough and breathlessne...

What are the CD34+ cells in benign peripheral nerve sheath tumors? Double immunostaining study of CD34 and S-100 protein.

To determine whether CD34 expression in nerve sheath lesions was found in a unique cell population or in a subset of nerve sheath cells, we performed double immunohistochemical staining using a standard avidinbiotin complex method with 2 separate color developing systems. We studied 40 neurofibromas and 16 neurilemomas. All lesions strongly expressed S-100 in nuclei and cytoplasm. CD34 was dete...

Immunophenotyping of Immune Cells in Peripheral Blood of TB Patient with Positive Smear Before Treatment

ABSTRACT Regarding cellular immunity function and macrophage system in tuberculosis infection control and also tuberculosis high spread in Gilan province and as many studies about tuberculosis has done in chronic and acute progressive process. This study was examined thirty persons smear positive with clinical symptoms and recognition infections expert before Treatment. Tuberculosis patients ...

CD34-positive cells: biology and clinical relevance.

Cellular expression of the CD34 antigen identifies a morph o l ogi c a lly and immu n o l ogi c a lly heterogeneous cell population that is function-a lly ch a racteri zed by the in vi tro c a p a bi l i ty to gen era te cl onal aggrega tes derived from early and late progenitors and the in vivo capacity to reconstitute the myelo-lymphopoietic system in a supralethally irradiated host.
