Abstract:

Forty three year old female patient was forwarded to us with the diagnosis of metastatic adenocarcinoma of unknown by the oncologist with a mass in the neck. In history, he said growing left neck mass in 5 months. Neck ultrasound (USG), neck CT and chest CT were done before coming to our clinics. Fine needle aspiration (FNA) results from mass were reported as metastatic adenocarcinoma. Patients PET was performed and hypermetabolic areas were found in the left cervical region and rectum. Two tumor biopsies were taken from rectum at different times for diagnostic and therapeutic purposes and reported as negative, therefore, neck dissection was planned. Round encapsulated mass with 3x2. 7x2. 5 cm was detected in left carotid bifurcation, intraoperatively. The mass was excised by working in subadventisyel. As pathology results, the mass was reported as paraganglioma, on the other hand, the neck dissection material was reported as reactive hyperplasia. Preoperative fine needle aspiration biopsy results can lead to incorrect diagnoses. The carotid body tumors can be misdiagnosed as malignancies in histopathological evaluation. We believe that the preoperative evaluation of the patient by a multidisciplinary team composed of oncologist, otolaryngologist, pathologist and radiologist will reduce this possibility.
