SOX10 vs S100 in IHC
Both stains can support melanocytic or Schwannian differentiation, but their staining patterns and background differ. Neither is specific enough to settle a case alone.
Reviewed SOURCE-REVIEWED GUIDETTF-1 vs Napsin A in IHC
TTF-1 is a nuclear marker and Napsin A is a cytoplasmic marker. Their combined interpretation can help in selected lung adenocarcinoma workups, with important exceptions.
Reviewed SOURCE-REVIEWED GUIDEKi-67 in Immunohistochemistry: What the Marker Shows
Ki-67 staining estimates the fraction of cells in the active cell cycle. The reported labeling index depends on which cells and areas are counted.
Reviewed SOURCE-REVIEWED GUIDECK7 vs CK20 in IHC
CK7 and CK20 are cytokeratin stains often considered as a pair. Their pattern can orient a differential, but it cannot establish a primary site on its own.
Reviewed SOURCE-REVIEWED GUIDEER vs PR in IHC
ER and PR are distinct hormone-receptor IHC tests. Both are assessed in tumor nuclei, but current breast-cancer reporting guidance gives ER-low results a specific category.
