[Amyloid tumors in soft tissues of the neck]

Tumorous amyloid deposits in the neck region of a 31-year-old man caused difficulties in the preoperative differential diagnosis of a tumorous process of the thyroid gland. Several tumorous amyloid deposits compressing and eroding the left nevus vagus and having no connection to the trachea or thyroid gland were removed. Such isolated tumorous amyloid deposits in the neck region have not been described before. Histologically no thyroid tissue was found. A medullar cancer of the thyorid gland that has to be excluded in such cases was not found.
