The incidence of getting an unsatisfactory smear while performing fine needle aspiration cytology is high when performed with the needle alone and when only limited material is obtained during the procedure. This reflects in the adequacy of material obtained and also creates confusion for the reporting cytopathologist. A major problem arises when most of the material that is obtained during a needle biopsy is trapped within the needle hub. This invasive procedure is generally done by the surgical pathologist, and it involves great skills and techniques to perform and also obtain adequate material from the hub of the needle. The material obtained during the procedure plays a vital role in obtaining a satisfactory smear and reduces the confusion during reporting. Thus, to obtain the material from the needle hub that is trapped, certain methods can be followed so that it helps in obtaining adequate material as well as reduces the needle passes given to the patient during the procedure.
