Gastric Ulcer and Perforation due to Mucormycosis in an Immunocompetent Patient.

Mucormycosis is a rare and life-threatening fungal infection that is associated with high mortality in immunocompromised individuals. Although it most commonly affects lungs and paranasal sinuses, cases of invasive mucormycosis of the gastrointestinal tract have also been reported. Gastrointestinal mucormycosis (GIM) is most commonly found in the stomach, colon, and ileum. Etiologies of GIM include ingestion of spores and penetrating abdominal trauma, causing mucocutaneous disruption. We present a case of an immunocompetent man who presented to our hospital after a gunshot wound to the abdomen. His hospital course was complicated with the development of invasive GIM in the form of a large gastric ulcer, which caused gastrointestinal bleeding and eventually perforation.

Imaging-Negative Hepatocellular Carcinoma Presents as an Intrabiliary Mass.

Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related death and one of the most prevalent cancers worldwide. HCC prognosis remains poor with an average survival rate between 6 and 12 months. Obstructive jaundice, as a main clinical feature, is uncommon in HCC. HCC with bile duct invasion is much rarer than HCC with vascular invasion. We present a case where a patient's HCC was diagnosed by endoscopic retrograde cholangiopancreatography and digital cholangioscopy because his HCC manifested as an obstructing lesion in the intrahepatic duct, but not in the liver.
