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.

Anaplastic thyroid carcinoma arising in long-standing multinodular goiter following radioactive iodine therapy: report of a case diagnosed by fine needle aspiration.

Background: Anaplastic thyroid carcinoma (ATC) is a highly aggressive, undifferentiated carcinoma that may arise on top of normal or abnormal thyroid. Making the diagnosis by fine needle aspiration (FNA) of the thyroid with a long-standing history of multinodular goiter (MNG) is not uncommon. We report a case discussing the cytopathologic findings and the relationship with long-standing goiter and thyroid exposure to radioactive iodine treatment.
