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.
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.
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.
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.
肝细胞癌(HCC)的骨转移通常见于晚期肝内HCC病程中。孤立性骨转移作为HCC的初始表现并不常见。
作者报告一例68岁男性,有长期饮酒史,出现上腹部疼痛、腹胀,背部右后外侧有一个坚硬、压痛的肿块。检查发现HCC伴孤立性转移至胸后壁。
HCC通常继发于慢性乙型和丙型肝炎感染,发生在慢性肝病背景下。骨转移的常见症状包括局部疼痛、神经表现、可触及的皮下肿块和病理性骨折。对于无已知潜在HCC的患者,免疫组织化学分析对于区分HCC与非HCC转移很重要。由于预后较差,治疗通常以姑息治疗为主。
孤立性肋骨肿块可能是转移性HCC的初始表现。因此,对于出现胸部疼痛性肿胀的患者,鉴别诊断时应考虑HCC伴骨转移。
