Best practice in thyroid pathology

Thyroid pathology is a specialist area but is often encountered by the general pathologist in a variety of forms including cytology, frozen sections, and resection specimens. In the thyroid gland, as for other endocrine organs, many aspects of diagnosis are unique to this area of histopathology; thus, the aims of this paper are to set out best practice guidelines which, although not entirely comprehensive, will be of practical use.
