A 34-year-old man visited the ENT clinc of Kobe University Hospital with a complaint of 3 months' duration of recent enlargement of a painless mass 6×8cm in size at the right side of the neck.Before the patient came to us, he had undergone an open biopsy at another clinic, and its histopathological examination revealed a malignant metastatic tumor. The primary lesion was not detected on the thorough examination not only of the head and neck area but also of the entire body.Although the primary lesion was not found, as the tumor had a histopathological malignancy, a radical neck dissection of the right side under general anesthesia was performed. The well-capsulated tumor about 3×2cm in size was located beneath the sternocleidomastoid and separated from the carotid artery. The histopathological examination of the removed specimen at Kobe University Hospital revealed a chemodectoma of the neck.
