Erratum: Pitman MB and Layfield LJ. Guidelines for pancreaticobiliary cytology from the Papanicolaou Society of Cytopathology: A review. Cancer Cytopathology doi: 10.1002/cncy.21427.

In Table 3, the “Mucicarmine” target should say “acid mucin” instead of “neutral mucin.” Also, on page 7, first paragraph, second column, a sentence should be corrected to say “Other mucin stains include mucicarmine stain for acid mucin and alcian blue…” The authors regret these errors.
