Hyoid Bone Metastases: An Unusual Case.

(1)

Background

Secondary tumors of the hyoid bone are extremely rare in clinics. In the literature, there is only one study about hyoid bone metastases from sigmoid adenocarcinoma. (2)

Methods

We report a case of hyoid bone metastases in a 78-year-old patient treated for rectum and sigmoid colon adenocarcinoma. (3)

Results

A mass excision surgery of a rounded osteolytic mass of 4.5 × 3.6 cm in size in the central part of the hyoid bone was performed under general anesthesia, according to the multidisciplinary tumor board recommendation. (4)

Conclusions

Hyoid bone metastases can occur in the rectum and sigmoid colon adenocarcinoma. A total body bone scintigraphy and CT examination are suggested to detect silent bone metastases in patients with a history of cancer and neck masses. The prognosis is good, but a regular follow-up is recommended.
