Hepatoid Adenocarcinoma Presenting as Pancreatitis

Hepatoid adenocarcinoma of the colon.

Hepatoid adenocarcinoma (HAC) is a rare extrahepatic adenocarcinoma that morphologically and immunophenotypically mimics hepatocellular carcinoma (HCC). We report the case of a 42-year-old woman with an extensive cancer history who presented with right-sided abdominal pain and lower gastrointestinal (GI) bleeding, and was ultimately diagnosed with colon adenocarcinoma. She underwent sigmoidecto...

Hepatoid adenocarcinoma of the gallbladder

Hepatoid adenocarcinoma is a rare variant of extrahepatic adenocarcinoma which behaves like hepatocellular carcinoma in morphology and functionality. We present a rare case of hepatoid adenocarcinoma of the gallbladder which invades deeply the liver bed, in a 59-year-old woman. Histologically, most of the mass in the gallbladder was composed of cells with eosinophilic cytoplasm arranged in a tr...

Hepatoid Adenocarcinoma of the Urachus

Hepatoid adenocarcinoma of the urachus is a rare condition. We present the case of a 51-year-old female who developed abdominal pain and hematuria. Pelvic magnetic resonance imaging (MRI) reported an urachal mass with invasion to the bladder that was resected by partial cystectomy. On light microscopy the tumor resembled liver architecture, with polygonal atypical cells in nest formation and tr...

Pancreatic Metastasis of Alveolar Rhabdomyosarcoma Presenting as Acute Pancreatitis

Choledochocele Presenting as Recurrent Pancreatitis

We report the case of a 31-year-old male with recurrent episodes of acute pancreatitis, subsequently discovered to have a rare type III choledochal cyst, also termed a choledochocele. This case demonstrates the utility of multiple imaging techniques to diagnose the correct etiology of the patient's pancreatitis, as well as to appropriately plan surgical intervention. For many years, endoscopic ...
