Fine-needle aspiration biopsy (FNAB) is a cheap and effective diagnosis process. It can be applied with imaging methods or often directly. In addition to the usual minor complications such as pain, irritation, rash around the area where biopsy is applied, major complications that threaten life such as carotid hematoma might also be seen rarely. A carotid hematoma case which emerged after a fine-needle aspiration biopsy in our clinic is presented.
