Abstract
Among 35,000 thyroid FNAB diagnoses made during 1989-2009, 135 PTC FNAB diagnoses were divided into 3 categories by expressed probability. Of the 75 PTC FNAB diagnoses, 71 were confirmed; the remaining 4 were hyperplastic goiters.
In the group of 45 cases with PTC, in which FNAB diagnosis was the next most probable differential diagnosis, 23 were confirmed. In the group of 15 cases, in which the PTC FNAB diagnosis was considered the less probable differential diagnosis, 3 PTCs were found.
FNAB diagnosis of PTC is not always possible, with success rate influenced by lesion type and size, accompanying diagnoses, representativeness of cytology sample and experience of the cytopathologist.
