Features and diagnostic accuracy of fine needle aspiration cytology of thyroid nodules: retrospective study from Oman.

Background: Fine needle aspiration cytology (FNAC) of the thyroid has been a reliable and cost-effective method for diagnosing thyroid disorders. Since FNAC results are usually operator dependent, there is a compelling need to explore FNAC accuracy among Omanis.

Objective: Describe cytological features of FNAC and assess FNAC accuracy compared to the postsurgical histopathology report.
