Chest wall mass as a sign of ignored hepatocellular carcinoma in an alcoholic cirrhotic patient: a case report

Abstract

Introduction and importance: Bone metastasis of hepatocellular carcinoma (HCC) is usually seen in the course of advanced intrahepatic HCC. Isolated bone metastasis as an initial manifestation of HCC is uncommon. Case presentation: The authors report a case of a 68-year-old male with a history of chronic alcohol consumption who presented with epigastric pain, abdominal distension, and a hard, tender lump on the right posterolateral aspect of his back. Investigation revealed HCC with isolated metastasis to the posterior thoracic wall. Clinical discussion: HCC usually develops secondary to chronic hepatitis B and C infection in the background of chronic liver disease. Common presenting symptoms of bone metastasis include local pain, neurological manifestations, palpable subcutaneous masses, and pathological fractures. An immunohistochemistry analysis is important to differentiate HCC from non-HCC metastasis in patients without known underlying HCC. Treatment is often directed towards palliative care as the prognosis is poor. Conclusion: An isolated rib mass can be an initial presentation of metastatic HCC. Thus, HCC with bone metastasis should be considered in the differential diagnosis in patients presenting with painful swelling in the thoracic region.
