Hepatoid carcinomas are a group of neoplasms with features resembling hepatocellular carcinomas. Although extremely rare, more cases have been noted to arise from various organs within the last decade. Differentiating these tumors when located in the biliary tree from cholangiocarcinoma is not only a radiologic challenge but also critical, because treatment modalities and operative strategies a...

Alpha-fetoprotein (AFP)-producing adenocarcinoma, histologically mimicking hepatocellular carcinoma (HCC), is a distinct entity known as hepatoid adenocarcinoma (HAC). Reported cases of HAC arising from the esophagus are extremely rare. Due to common liver metastasis and elevated AFP levels in patients with esophageal HAC, differentiation of HAC with liver metastasis from HCC could be challengi...
Primary hepatoid carcinoma of the ovary (HCO) is a rare type of ovarian tumor that resembles hepatocellular carcinoma both histologically and immunohistochemically in its staining for alpha-fetoprotein (AFP). We describe a 51-year-old woman who presented to our hospital complaining of abdominal pain. Computed tomography scan revealed a large tumor in the pelvis. She underwent total hysterectomy...
Hepatocellular carcinomas rarely metastasize to the ovaries. To our knowledge, only nine cases of metastatic hepatocellular carcinoma of the ovary have been reported in the literature. Here, we present an additional case in which an ovarian lesion was the initial presentation in a 43-yearold female patient. An exploratory laparotomy revealed a left ovarian solid mass measuring 6.5×4.0×3.5 cm, w...
The diagnosis of hepatocellular carcinoma (HCC) relies on imaging tools and biopsy. It usually does not present to be a challenge.Here we report the case of a 69-year-old patient with HCC, initially mistaken for a gastric hepatoid adenocarcinoma (HAC), with a favorable outcome after neoadjuvant chemotherapy.The initial presentation (clinical signs, morphological features, and histological findi...
Hepatoid carcinoma of the ovary (HCO), a rare invasive malignant tumor composed mainly of epithelioid cells, presented with unilateral or bilateral ovarian masses and elevated serum α-fetoprotein (AFP), has been found mainly in post-menopausal women. We hereby report on the case of a 53-year-old Chinese woman who presented with abdominal distension and a lower abdominal mass with high serum lev...
