subcutaneous panniculitis-like t-cell lymphoma (sptcl) is an infrequent cytotoxic t-cell lymphoma of the skin with a unique immunophenotypic profile. here we describe this lymphoma in a 30-year-old iranian woman. she presented with periorbital edema, mandibular swelling with edematous areas on her face and two small lymph nodes (6-7mm) in the cervical area. histopathological findings revealed l...
Immunohistochemical Comparison of p53 Expression, Intensity and Distribution in Different Papillary Urothelial Cancers
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
The aim of this study was the identification of novel biomarker candidates for the diagnosis of cholangiocellular carcinoma (CCC) and its immunohistochemical differentiation from benign liver and bile duct cells. CCC is a primary cancer that arises from the epithelial cells of bile ducts and is characterized by high mortality rates due to its late clinical presentation and limited treatment opt...
Ueda, Junji, Hiroshi Saito, Hiroaki Watanabe, and B. Mark Evers. Novel and quantitative DNA dot-blotting method for assessment of in vivo proliferation. Am J Physiol Gastrointest Liver Physiol 288: G842–G847, 2005. First published November 11, 2004; doi: 10.1152/ajpgi.00463.2004.—Immunohistochemical assessment of 5-bromo-2-deoxyuridine (BrdU) in tissue sections is a widely used method to evalua...
CCND1 gene amplification and cyclin D1 protein overexpression are indicators for poor prognosis in invasive head and neck carcinomas. Increased CCND1 gene dosage is a more sensitive prognostic factor than protein overexpression as evaluated by conventional immunohistochemical techniques. Qualitative immunohistochemistry cannot distinguish cyclin D1 overexpression accompanied by amplification of...
BACKGROUND Fine-needle aspiration of breast cancer often provides moderate cellular material that is representative of the tumors. These samples can be used not only for cytological diagnosis but also to obtain information on the prognosis and likely response to therapy by using immunohistochemical staining studies. METHODS We assessed the degree of correlation between prognostic biologic mar...
The aim of this study is to investigate the predictive value of proliferative activity assessment and E-cadherin expression by means of immunohistochemistry in identifying patients with laryngeal squamous cell carcinoma at a high risk for occult node metastasis. Thirty consecutive patients treated for laryngeal carcinoma with false clinically negative nodes (occult metastases, pN+) between the ...
PURPOSE Immunohistochemistry (IHC) and microsatellite instability (MSI) analysis can be used to identify patients with a possible DNA mismatch repair defect [hereditary nonpolyposis colorectal carcinoma (HNPCC)]. The Bethesda criteria have been proposed to select families for determination of MSI. The aims of this study were to assess the yield of MSI analysis in families suspected for HNPCC, t...
