S-100 Protein Information for Pathologists


95 amino acid calcium-binding protein first purified from placenta in 1992 (Eur J Biochem 1992;207:541); 95 amino acid calcium-binding protein; may initiate carcinogenesis in some epithelial tumors. Caution: S100 (the neural / melanocytic marker) is also described as S100p or S100P in the literature. Pathophysiology Intracellular S100P interacts with ezrin, and extracellular S100P activates the receptor for advanced glycation endproducts. Associated with aggressive disease in peripheral intrahepatic cholangiocarcinoma (Am J Surg Pathol 2011;35:590).

Common Uses By Pathologists:

Diagnose pancreatic adenocarcinoma in FNA specimens (Am J Clin Pathol 2008;129:81, Diagn Cytopathol 2011 Apr 28 [Epub ahead of print]). Differentiate bile duct adenocarcinoma from reactive lesions at biopsy, as part of a immunohistochemical panel with pVHL and IMP3 (Hum Pathol 2010;41:1210). Differentiate urothelial carcinoma (S100P+ in 78-86%) from prostatic adenocarcinoma (S100P-). Possible biological indicator (due to downregulation) of cadmium toxicity in placentas (Sci Total Environ 2011;410:53). Microscopic (histologic) images
