Description générale

Anti-Cytokeratin, 34betaE12 is an antibody to high molecular weight cytokeratin that reacts with all squamous and ductal epithelium and stains carcinomas. This antibody recognizes cytokeratins 1,5,10, and 14 that are found in complex epithelia. Anti-Cytokeratin, 34betaE12 shows no reactivity with hepatocytes, pancreatic acinar cells, proximal renal tubules, or endometrial glands; there has been no reactivity with cells derived from simple epithelia. Mesenchymal tumors, lymphomas, melanomas, and neural tumors are unreactive with this antibody with some exceptions. Anti-Cytokeratin, 34betaE12 does label myoepithelial cells and has been shown to be useful in distinguishing prostatic adenocarcinoma from hyperplasia of the prostate. This antibody has also been useful in separating benign from malignant intraductal breast proliferations.

Immunohistochemistry with antibodies for high-molecular-weight cytokeratin labels basal cells and is used as an ancillary study in diagnosing prostate carcinoma, which reportedly lacks expression of high-molecular-weight cytokeratin. A recent report questioned the specificity of this marker, describing immunopositivity for high-molecular-weight

Basal cell-specific anti-cytokeratin antibody (34 beta E12) decorates the basal cells of benign prostatic epithelium by standard immunohistochemical techniques, whereas adenocarcinoma of the prostate lacks immunoreactivity with this antibody. We reviewed our experience with this antibody to determine its utility

A variety of studies have investigated the role of low molecular weight (LMW) and high molecular weight (HMW) cytokeratin (CK) expression in the normal breast and invasive breast carcinomas. A few studies with small numbers of cases have addressed this

Histologic review of 48 radical prostatectomy specimens containing both prostatic adenocarcinoma (PC) and high-grade prostatic intraepithelial neoplasia (PIN) resulted in 23 cases containing neoplastic cribriform gland (CGs) at the periphery or within PC fields. The histologic characteristics of CG PIN
