Anatomic Pathology / IMMUNOHISTOCHEMICAL ANALYSIS OF BRONCHIOLOALVEOLAR ADENOCARCINOMAS Mucinous and Nonmucinous Bronchioloalveolar Adenocarcinomas Have Distinct Staining Patterns With Thyroid Transcription Factor and Cytokeratin 20 Antibodies

We studied 14 mucinous and 26 nonmucinous bronchioloalveolar adenocarcinomas (BACs) with thyroid transcription factor (TTF), cytokeratin (CK) 7, CK20, and villin to characterize their staining patterns with these antibodies and identify staining differences between the neoplasms. We also stained 11 mucinous colon adenocarcinomas with the same antibodies to compare their reaction patterns with m...

Anatomic Pathology / CDX2 SEPARATES MUCINOUS BRONCHIOLOALVEOLAR FROM METASTATIC MUCINOUS COLORECTAL CARCINOMA Usefulness of Cdx2 in Separating Mucinous Bronchioloalveolar Adenocarcinoma of the Lung From Metastatic Mucinous Colorectal Adenocarcinoma

We studied the diagnostic value of Cdx2 to distinguish mucinous bronchioloalveolar carcinoma from mucinous colorectal adenocarcinoma metastatic to the lung. We retrieved 92 via the hospital computer system, including 30 mucinous bronchioloalveolar carcinomas, 32 nonmucinous bronchioloalveolar carcinomas, and 30 mucinous colorectal adenocarcinomas metastatic to the lung. All cases were confirmed...

Differential expression of cytokeratins 7 and 20 and thyroid transcription factor-1 in bronchioloalveolar carcinoma: an immunohistochemical study in fine-needle aspiration biopsy specimens.

We studied the staining patterns of bronchioloalveolar carcinoma (BAC) with antibodies to cytokeratin (CK) 7, CK20, and thyroid transcription factor-1 (TTF-1) to determine the diagnostic usefulness of this panel in differentiating BAC from metastatic adenocarcinoma in material obtained by fine-needle aspiration biopsy (FNAB) of the lung. We identified 16 cases of BAC. Of these, 6 were mucinous,...

Cytokeratin 7/20 Expression Patterns and Association with Prognostic Varia- Bles in Gastric Adenocarcinomas

Aim: The histologic features, potential behavior, genetic pathways, epidemiological characteristics and response to treatment of gastric carcinomas, is showing heterogeneity. Cytokeratin (CK), an intermediate-sized filament detected primarily in epithelial cells. Most commonly used CKs in immunohistochemical studies are CK7, CK20 and these molecules are used as a markers to help identify the si...

Immunoexpression of HBME-1, High Molecular Weight Cytokeratin, Cytokeratin 19, Thyroid Transcription Factor-1, and E-cadherin in Thyroid Carcinomas

To examine the immunohistochemical alterations associated with the histological dedifferentiation of thyroid carcinomas, we performed staining for HBME-1, high molecular weight cytokeratin (HCK), CK 19, thyroid transcription factor-1 (TTF-1) and E-cadherin (E-CD) on 125 various types of thyroid carcinomas. The HBME-1 staining was strong and diffuse in follicular carcinoma (FC), papillary carcin...
