Surgical Oncology, All India Institute of Medical Sciences, New Delhi, New Delhi, IND.
We report a rare case of adenosquamous carcinoma of the gall bladder (GB) causing portal vein tumor thrombus. A 40-year-old gentleman presented with acute-onset right upper abdominal pain. Ultrasonography revealed multiple calculi in the GB with wall thickening, suggesting acute cholecystitis.

December 2024
Department of Pathology, Seoul National University Bundang Hospital, Seongnam, Korea.
Background: A right adrenal gland may present in the form of adreno-hepatic fusion (AHF), in which the adrenal cells are interspersed among the hepatocytes without septation. This rare, naturally-occurring phenomenon may be associated with preoperative misdiagnosis. We present two cases of adrenal tumor in patients with AHF that were misdiagnosed, despite thorough preoperative work-ups.

Introduction: Reports of pseudoaneurysms associated with biliary self-expandable metallic stent (SEMS) placement have been increasing. Recently, cases of hepatic pseudoaneurysm rupture caused by double pigtail plastic stents (DPS) have also been reported. The symptoms of pseudoaneurysms are often non-specific, and many cases are diagnosed only after rupture.

Bioinformatics Core Facility, Lyda Hill Department of Bioinformatics, Department of Pathology University of Texas Southwestern Medical Center, Dallas, TX.
The cholangioblastic variant of intrahepatic cholangiocarcinoma is a distinctive neoplasm that typically affects young women without underlying liver disease. Morphologically, it demonstrates solid, trabecular, and tubulocystic architecture, biphasic small cell-large cell cytology, and immunoreactivity for inhibin, neuroendocrine markers, and biliary but not hepatocellular markers. In 2021, our group identified a characteristic NIPBL::NACC1 gene fusion in cholangioblastic cholangiocarcinoma, and since then ~20 genetically confirmed cases have been reported in the literature.
