Purpose: To report a case of primary hepatoid adenocarcinoma of the orbit.
Observations: An adult patient was referred for evaluation of an orbital mass. Histopathology of the orbital biopsy indicated a carcinoma with hepatoid features. Laboratory studies revealed normal liver function tests, elevated serum alpha-fetoprotein, and whole-body positron emission tomography/computed tomography scan showed no evidence of liver involvement or an alternative primary origin.
Conclusions And Importance: To the authors' knowledge, this is the first reported case of primary hepatoid adenocarcinoma of the orbit.

Primary hepatoid adenocarcinoma (HAC) of the uterus is a particular tumour that bears high similarity to hepatocellular carcinoma histologically, and may easily be misdiagnosed because it is rare if you don' t remember it. In this report, we describe two cases of alpha-fetoprotein (AFP)-producing HAC of the uterus. Case 1 was a 69-year-old postmenopausal woman who was presented to the hospital for a medical examination.

Background: Hepatoid adenocarcinoma of the stomach (HAS), a subtype of gastric cancer (GC), includes multiple tumor components, such as enteroblastic and tubular adenocarcinoma components. However, which component mostly contributes to the aggressive behavior of HAS remains unclear. Moreover, the role of tumor-associated macrophages (TAMs) has not been explored in HAS.

Primary hepatoid adenocarcinoma of the lung (HAL) is an exceptionally rare subtype of lung cancer that mimics the morphology and biological behavior of hepatocellular carcinoma. Although reports in the literature are limited, HAL is known for its high malignancy and poor prognosis, thus drawing increasing attention. We present the case of a patient with a mass-like consolidation with central necrosis initially misdiagnosed as inflammation at another medical institution despite a percutaneous lung biopsy.
