Tru-Cut®, core, lance or punch biopsy

It «is when a core of tissue (about 2 millimeters thick) is taken from a lump or tissue using a special needle. Although it can be done in certain circumstances under local anesthetic it is generally performed under a general anesthetic [1].» «The Tru-Cut® biopsy device helps you manually capture high-quality tissue samples with minimal patient trauma [2].» It is a «minimally invasive technique (transcutaneous punctures) for collecting tissue samples by means of special needles that remove a hemicylinder of a lesion, allowing its histological evaluation [3].» «Tru-Cut® biopsy, also called a core, lance, or punch biopsy with a tissue-cutting needle, provides tissue sampling by a percutaneous puncture. These instruments consist of a cutting cannula and a needle with a stylet tip and a semicylinder slot to collect a fresh tissue fragment [4,5]. This technique is normally used in cases when fine-needle aspirates cannot provide a definite diagnosis [5].»
«Tru-Cut® biopsy was first used in 1855 by Duchenne to diagnose Duchenne muscular dystrophy [5].»
