Objectives We compared the complications and diagnostic adequacy of ultrasound (US)‐guided core needle biopsy (CNB) for head and neck mass lesions between patients who did and did not receive antiplatelet/anticoagulation therapy. Methods This study was designed as a prospective case study including 146 consecutive patients who underwent US‐guided CNB for head and neck mass lesions. Of these, 32 patients were undergoing antiplatelet/anticoagulation therapy involving aspirin, clopidogrel, cilostazol, and warfarin. Results None of the patients had clinical bleeding/hematoma in either group. Subclinical bleeding/hematoma recognized only by a US examination was not significantly different between the groups ( P = .229). No other complications were noticed. The rate of unsatisfactory sampling was also not different between the groups ( P > .999). Furthermore, when patients receiving aspirin (n = 18) were reclassified into the no–antiplatelet/anticoagulation therapy group, there was still no significant difference in the incidences of complications compared with the patients receiving clopidogrel, cilostazol, or warfarin (n = 14). Conclusions Our study suggests that US‐guided CNB is safe and provides good diagnostic results without necessitating the discontinuation of antiplatelet/anticoagulation therapy in patients with head and neck mass lesions. However, as this was a preliminary study, the cohort was relatively small. Larger studies are needed to confirm our findings.
