Pancoast syndrome and hepatocellular carcinoma – a rare association
Keywords:
Pancoast´s syndrome, hepatocellular carcinoma, bone metastasis, HCVAbstract
Pancoast´s syndrome (PS) includes all signs and symptoms resulting from a tumor affecting the pulmonary apex and adjacent
structures. Its main clinical feature is pain in the shoulder, supra-clavicular and arm along with the distribution of the ulnar nerve.
The majority of cases are caused by non-small-cell bronchogenic
carcinoma. Etiologic diagnosis is mostly achieved by histological
examination of a percutaneous transthoracic needle biopsy. PS
is a rare manifestation of a hepatocellular carcinoma (HCC). HCC
is the most common primary liver tumor having a multifactorial
etiology and high mortality rates. It often spreads itself to the lungs
and regional lymphatic nodes; bone metastases are uncommon
(2-20%); Patients with HCC can experience bone pain with no
signs of hepatic dysfunction.
