    9. Mucin staining - MUC2 (Goblet cell marker), MUC5AC (foveolar marker), MUC6 (antral/pyloric gland marker)

    Mucin staining

    MUC2 Epithelial mucin expressed in intestinal goblet cells and airway epithelium; gene is at 11p15.5
    Relatively specific for predicting colorectal origin for Paget disease (Am J Surg Pathol 2001;25:1469)
    Gel forming MUC2 mucin may act as barrier to prevent infiltration of malignant cells in breast mucinous / colloid carcinoma
    Positive staining: intestinal and airway epithelium; mucinous carcinoma of colon, breast, pancreas, ovary and stomach
    Negative staining: stomach, breast ductal and lobular carcinomas
    MUC3 Upregulated by steroid hormones in vitro
    Positive staining: invasive breast carcinoma, gastric carcinoma (associated with poor prognosis)
    MUC4 Transmembrane or membrane bound mucin that provides a protective layer of mucus
    Normally acts as barrier to apical surface of epithelial cells, playing a protective and regulatory role
    Positive staining - normal: tracheobronchial mucosa, colon, stomach, cervix and lung; normal salivary glands
    Positive staining - disease: pancreatic, colonic, pulmonary and gastric carcinoma; sclerosing epithelioid fibrosarcoma (Am J Surg Pathol 2014;38:1538, Am J Surg Pathol 2012;36:1444)
    MUC5AC. Also known as MUC5 (GeneCards) Protects epithelium Positive staining - normal: stomach (foveolar epithelium of body and antrum), tracheobronchial mucosa, endometrium (mucinous metaplasia, eosinophilic change / metaplasia (Mod Pathol 2005;18:1243), surface syncytial change, ciliated change in 52%)
    Positive staining - disease: extramammary Paget disease but not mammary Paget disease or normal breast tissue (Am J Surg Pathol 2001;25:1469); mucinous carcinoma of ovary, diffuse type gastric carcinoma (83%)
    Negative staining: normal breast tissue
    MUC6 Produces protective glycoprotein coat for gut epithelia
    Positive staining - normal: stomach (pyloric glands), gallbladder, colon and endocervix
    Positive staining - disease: invasive ductal carcinoma of breast, gastric carcinomas
    Negative staining: normal breast tissue

    In a cohort of 97 gastric cancers 30% expressed MUC5AC and MUC6 (gastric phenotype), 40% expressed MUC5AC, MUC6 and MUC2 (gastrointestinal phenotype), 10% expressed MUC2 alone (intestinal phenotype) and 20% lacked all markers (null phenotype). (J Surg Oncol. 2008;98:124-129)
