Partial resection and reconstruction of the sternum for treatment of metachronous sternal metastasis of thyroid carcinoma: A case report.

RATIONALE: Metachronous sternal metastasis of thyroid carcinoma was a rare disease. There was no consensus in the treatment for bone metastasis after the initial thyroid carcinoma surgery.

PATIENT CONCERNS: A 53-year-old female patient was hospitalized due to recurrent dull chest pains, with a history of radical right side thyroid carcinoma 4 years ago. On examination, there was an irregular mass on the lower left half of the sternum. Computerized tomography scan showed sternal bone destruction with a soft tissue mass.

DIAGNOSES: Metachronous sternal metastasis of thyroid carcinoma.

INTERVENTIONS: Partial resection of the sternum and reconstruction with a titanium alloy mesh were performed.

OUTCOMES: After a 3-year follow-up, the patient had no recurrence.

LESSONS: Surgical resection may be a sufficient treatment for metachronous sternal metastasis of thyroid carcinoma. Biosynthesis material mesh is preferred to be used.
