Soft-Tissue Localization of Hepatoid Adenocarcinoma: First Case Report

Soft-Tissue Localization of Hepatoid Adenocarcinoma: First Case Report

Hepatoid adenocarcinoma (HAC) is a rare type of extrahepatic cancer, whose pathologic features are indistinguishable from those of hepatocellular carcinoma. About thirty cases, nearly half of which occurring in the lung, have been described in patients with a normal liver. No imaging features are typical enough to allow a correct diagnosis. A localization of HAC in the soft tissues of the shoul...

Pulmonary hepatoid adenocarcinoma: report of a case

Hepatoid adenocarcinoma (HAC) is a rare neoplasm with aberrant hepatocellular differentiation. HAC occurs in extrahepatic organs such as the gastrointestinal tract, testes, ovaries, and lungs and frequently produces alpha-fetoprotein. A 69-year-old patient was diagnosed clinically with T2aN0M0, stage IB, non-small cell lung carcinoma. Because the tumor showed tight adhesion to the chest wall, w...

Hepatoid Adenocarcinoma of the Anterior Skull Base: A Case Report

We report the first case of hepatoid adenocarcinoma of the skull base, as well as the first reported case in the head and neck region. Hepatoid adenocarcinoma is a rare, aggressive, extrahepatic malignancy with a distinct morphological similarity to hepatocellular carcinoma, in the absence of primary hepatic disease. A 45-year-old man presented with sinus headaches and retro-orbital pain and wa...

[Hepatoid adenocarcinoma of the lung: a case report].

A case of a 71-year-old man with dyspnea attacks, weight loss and astheno-adynamia syndrome is presented. A 7.7 x 6.4 cm well-delineated tumor is found intraoperatively in the superior lobe of the left lung towards the posterior mediastinum. The tumor cells resemble hepatocytes histologically and show expression for alpha-fetoprotein. Diagnosis primary hepatoid lung adenocarcinoma is made. Peri...
