Malignant Seeding of the Tract after Thin-Needle Aspiration Biopsy

Abstract
Fine-needle aspiration biopsy is an established technique for cytodiagnosis of malignant neoplasms, yielding a high rate of positive tissue with negligible local sequelae. A case of needle tract seeding following this biopsy technique in a patient with an unresectable pancreatic carcinoma is reported. Because of the rarity of this occurrence, the procedural indications remain unaltered.
