Best practices in diagnostic immunohistochemistry: pleomorphic cutaneous spindle cell tumors.
CONTEXT Pleomorphic cutaneous spindle cell tumors can be difficult to distinguish solely on histologic grounds. The use of ancillary immunohistochemical studies can greatly assist in this differential diagnosis. OBJECTIVE To review histologic and immunohistochemical aspects of cutaneous spindle cell tumors and discuss a basic panel of markers to assist in the differential diagnosis. DATA SO...
متن کاملDiagnostic Value of Calretinin and S100 Immunohistochemistry in Hirschsprung's Disease
Background Rectal biopsy and its histopathological study with hematoxylin and eosin (HE) is the gold standard for Hirschsprung's disease (HD) diagnosis. However, there are some limitations in the diagnosis of ganglion cells in HE approach. Recently, it was reported that the utility of Calretinin is a reliable ancillary immunohistochemistry (IHC) test for HD diagn...
متن کاملImmunohistochemistry of Inflammatory myofibroblastic tumors
Background: Inflammatory myofibroblastic tumor (IMT) or inflammatory pseudotumor is a tumoral lesion which can be seen in all age groups and in all internal organs. It is in differential diagnosis with some important neoplasms such as Leiomyosarcoma, Rhabdomyosarcoma, and Sarcomatoid carcinoma. Differentiation between these tumors requires a special diagnostic tool such as Immunohistochemistry ...
متن کاملIntracanalicular meningioma: diagnostic by immunohistochemistry.
The meningioma (ME) was originally described by Virchow in 1863 as a tumor originating from meningothelial cells that are usually found within leptomeninges and the choroid plexi of the ventricles, with a preference for the supratentorial area. Any area that is covered by the leptomeninges, however, is potentially a site of origin for meningiomas. The first report of an exclusively intracanalic...
متن کاملQuantitative Analysis of Immunohistochemistry in Melanoma Tumors
Identification of positive staining is often qualitative and subjective. This is particularly troublesome in pigmented melanoma lesions, because melanin is difficult to distinguish from the brown stain resulting from immunohistochemistry (IHC) using horse radish peroxidase developed with 3,3'-Diaminobenzidine (HRP-DAB). We sought to identify and quantify positive staining, particularly in melan...
