Chest Wall Swelling in a Baby Boomer: An Unusual Presentation of Primary Hepatocellular Carcinoma.

Primary hepatocellular carcinoma (HCC) is one of the most frequently diagnosed cancers in adult men and a leading cause of cancer-related deaths worldwide. It also has an association with patients with hepatitis C-related cirrhosis. HCC usually metastasizes within the liver as well as to the lungs, regional lymph nodes, and adrenal glands, whereas the involvement of the chest wall and thoracic musculoskeletal system are more unusual. Herein, we report the case of a 58-year-old man who presented with swelling of the right anterolateral lower chest wall. The final diagnosis was primary HCC with distant metastases involving the right anterolateral ribs and left scapula. Such a presentation of extrahepatic HCC of this size and at this site is unique and has never before been reported in the literature. It reinforces the urgency and importance of screening all adults (18 years and above), particularly baby boomers, because three out of 100 have been infected with hepatitis C, at least once in their lifetime. It is also a wake-up call, as the incidence of primary HCC secondary to hepatitis C-associated cirrhosis has doubled, with a resultant increase in mortality. This HCC-related death might have been prevented if the patient had been screened for hepatitis C virus in his lifetime, as recommended by the American Association for the Study of Liver Diseases. We also discuss the latest developments in the diagnosis and management of HCC.
