Mammaglobin Information for Pathologists
Belongs to the family of small epithelial secretory proteins (secretoglobins) of the uteroglobin / Clara cell protein family. Uses by pathologists Highly specific for most breast cancers; useful to detect circulating or metastatic breast cancer (Arch Pathol Lab Med 2003;127:1330, Int J Clin Exp Pathol 2009;2:384, Mod Pathol 2010;23:654). Superior to GCDFP15 (Arch Pathol Lab Med 2008;132:239). Positive in endometrial and endocervical specimens (benign and malignant) (Int J Gynecol Pathol 2008;27:418).
Notable Clinical Features:
While some expression is seen in normal breast, its expression is markedly increased in breast carcinoma (positive expression has been reported in 48 - 72.1% of mammary adenocarcinomas) and is directly correlated with a higher grade. Also, mammaglobin expression is said to be higher in lobular carcinomas than ductal carcinomas and in ER positive tumors. Case reports 62 year old woman with solitary uterine metastasis of invasive lobular carcinoma (J Med Case Rep 2015;9:47). Microscopic (histologic) images
Common Uses By Pathologists:
Highly specific for most breast cancers; useful to detect circulating or metastatic breast cancer (Arch Pathol Lab Med 2003;127:1330, Int J Clin Exp Pathol 2009;2:384, Mod Pathol 2010;23:654). Superior to GCDFP15 (Arch Pathol Lab Med 2008;132:239). Positive in endometrial and endocervical specimens (benign and malignant) (Int J Gynecol Pathol 2008;27:418). Has limited utility in medullary and metaplastic breast cancers (Am J Clin Pathol 2012;137:747). Useful to differentiate mammary analogue secretory carcinoma (MASC) from secretory carcinoma of breast (Hum Pathol 2013;44:1982).
