Thyroid lesions are one of the common conditions encountered in clinical practice. It is difficult to clinically evaluate & reach to the correct diagnosis. Hence it is essential that a correct diagnosis is made as early as possible. The book contains cytomorphological details of lesions of thyroid with recently updated 2008 Bethesda Guidelines for thyroid FNAC. It will certainly be helpful for pathologists for reporting thyroid cytology cases as well as for clinicians to decide further line of management of the patients. The book as well covers technical aspects of performing thyroid FNAC. We hope this book will be beneficial to all practicing pathologists as well as learners in pathology field and the post graduates.
