Abstract

An osseous choristoma is a benign tumor consisting of regular bone tissue in an irregular localization. Choristomas in the head and neck region are rare. Most frequently, they are found in the region of the tongue or oral mucosa. There are also very few reports on osseous choristomas in the submandibular region. We present the case of a woman with a large, caudal osseous choristoma within the lateral cervical triangle. Literature review is given about all of the reported cases in the region of the neck. The pathogenesis is yet unexplained. Our case supports the theory that the development of an osseous choristoma is a reaction to a former trauma. Cervical osseous choristomas are seldom, but they represent an important differential diagnosis when dealing with a cervical tumor.

Summary

Introduction

An osseous choristoma is a benign tumor consisting of regular bone tissue in an irregular localization [1]. Our report refers to a 46-year-old female patient who presented to our hospital She had noticed a firm, spaceoccupying lesion in the left cervical soft tissue that had been increased in size slowly over a period of several months. In the course of our literature research, we did not encounter a single published case of an osseous choristoma in the caudal region of the lateral cervical triangle. E synopsis of the few published cases in the region of the cervical soft parts shows a deviating tendency In this localization, osseous choristomas seem to occur with the same frequency in men and women. Ere are various clinical differential diagnoses of head and neck masses at the caudal region of the lateral cervical triangle. In knowledge of the computertomographic findings, the amount of differential diagnoses is reduced to bony
