[Sternal metastasis revealing hepatocarcinoma].

INTRODUCTION

Bone metastasis from hepatocarcinoma are rare, their elective seats are the ribs, the vertebra and rarely the sternum. We report a case of a sternal metastasis which makes discovery of a hepatocarcinoma.

EXEGESIS: A 64 year-old man, alcoholic with a previous history of jaundice who developed since 1999 an anterior chest tumor with excellent clinical condition. Laboratory examination showed cytolysis, cholestasis, positive antihepatitis C virus antibodies and elevated serum alphafetoprotein level. Standard radiography and computed tomography of the chest showed an osteolytic lesion of the sternum spread to the adjacent soft tissues and voluminous right hepatic lesion. Pathologic examination of the sternal tumor concluded to a differential adenocarcinoma. Etiologic investigations to find the primitive tumor were negative. Operative procedure was not possible in consideration of the infiltration of the tumor and its situation near the main blood vessels. Radiotherapy gives rise to partial regression of the tumor. A second reading of the tumor biopsy established the diagnosis of metastasis from a hepatocellular carcinoma. The patient died 22 months after the appearance of the sternal metastasis.

CONCLUSION

Hepatocarcinoma is rarely disclosed by a sternal metastasis, our case-report is particular by its prolonged survival and the good clinical condition during its follow up.
