Comparison of needle-core (Trucut) biopsy and surgical biopsy for the diagnosis of cutaneous and subcutaneous masses: a prospective study of 51 cases (November 1997-August 1998).
Cutaneous or subcutaneous masses in 51 dogs and cats were examined by needle-core (i.e., Trucut) biopsy, and results were compared to results of surgical biopsy to assess the accuracy of the former. Needle-core specimens obtained before surgical biopsy were submitted to a single pathologist who evaluated both samples and was blinded to the results of surgical biopsy when evaluating the Trucut specimen. The results indicate that needle-core biopsy can accurately predict surgical biopsy. Thus, needle-core biopsy performed before surgical excision of masses can facilitate planning and reduce the need for numerous surgical procedures. Needle-core biopsy can direct appropriate treatment of nonmalignant masses.
