Evaluation of endocrine neoplasms using fine needle aspiration biopsy

Fine needle aspiration biopsy (FNAB) has established itself as a safe and r eliable diagnostic modality that is now routinely employed in the evaluatio n of endocrine tumors. Although FNAB provides specific diagnoses in the maj ority of cases, certain processes may not be readily distinguished by cytom orphology alone. Akin to the contributions of immunochemistry to diagnostic pathology, molecular diagnostics is now becoming an integral part of patie nt management. Molecular pathology may provide information regarding the di agnosis, prognosis, and therapy of numerous lesions. It is anticipated that further research and improvements in technology will result in the develop ment of sensitive and specific tests that will enhance the management of th e endocrine patient.
