Specimen collection and preparation in fine-needle aspirations in children

Fine-needle aspiration is of proven benefit in the pediatric population. For the procedure to be of maximum benefit, several aspects unique to children and pediatric lesions must be taken into account. Based on the experience of approximately 2,500 fine-needle aspirations performed in children over a 17-year period, we discuss techniques pertaining to specimen collection and preparation, including adequate control of the patient and selective triage of aspirates.
