ProExC triage of atypical glandular cells on liquid-based cervical cytology specimens.

Objective: Morphologic distinction between atypical glandular cells not otherwise specified (AGC-NOS) and AGC-favor neoplasia (AGC-FN) can be difficult. Distinction between these entities is important as the American Society for Colposcopy and Cervical Pathology 2006 consensus guidelines state that management of AGC-NOS differs from that of AGC-FN. The objective of this study was to determine the potential role of ProExC immunocytochemical triage of AGC-NOS.
