Peritoneal malignant mesothelioma (PMM), and primary peritoneal serous carcinoma (PPSC) and reactive mesothelial hyperplasia (RMH) of the peritoneum. Immunohistochemical and fluorescence in situ hybridisation (FISH) analyses.
Tokorozawa, Japan. In J Clin Pathol, Feb 2016
METHODS: To help differentiate PMM from PPSC and RMH, we used immunohistochemistry to examine mesothelial-associated markers (calretinin, AE1/AE3, CK5/6, CAM5.2, D2-40, WT-1, HBME1, thrombomodulin), adenocarcinoma-associated markers (CEA, BerEP4, MOC31, ER (estrogen receptor), PgR, TTF-1, Claudin-4, Pax8), and malignant-related and benign-related markers (epithelial membrane antigen (EMA), desmin, GLUT-1, CD146 and IMP3), and FISH to examine for homozygous deletion of 9p21.

Mucinous Variant of Follicular Carcinoma of the Thyroid Gland: Case Report and Review of the Literature.
Novi Ligure, Italy. In Int J Surg Pathol, Dec 2015
We report the fourth case of mucinous variant of follicular carcinoma displaying a minimally invasive tumor with diffuse expression of thyroglobulin, TTF-1, CD56, PAX-8, cytokeratins 7 and 19, in the absence of monoclonal carcinoembryonic antigen (CEA), cytokeratin 20, chromogranin, HBME-1, P63 expression, and BRAF gene mutation, in a 51-year-old woman who is alive without signs of disease 13 months after total thyroidectomy, bilateral neck dissection, and radioactive iodine.
San Antonio, United States. In Arch Pathol Lab Med, Aug 2015
Immunohistochemical stains (cytokeratin, parathyroid hormone, thyroid transcription factor 1, tyrosine hydroxylase, chromogranin A, synaptophysin, S100, calcitonin, carcinoembryonic antigen) are essential in establishing the diagnosis.
Cutaneous metastases from gastric adenocarcinoma 15 years after curative gastrectomy.
Nanjing, China. In An Bras Dermatol, May 2015
They were stained positive for villin, CDX-2, CKpan (AE1/ AE3), CEA, CK8/18, CK19, CK7, EMA, Ki-67 (50%), and negative for S-100, CK20, CD34, GCDFP-15 and TTF-1.
