A Rare Case of Hepatocellular Carcinoma Presenting as a Massive Abdominal Hematoma and Shock: A Case Report.

Hepatocellular carcinoma (HCC) has an affluent blood supply stemming from the hepatic artery. Subsequent spontaneous tumor rupture can lead to massive abdominal hematoma and shock, a rare fatal gastrointestinal incident. The diagnosis of rupture is complicated, with most patients presenting with abdominal pain and shock. Prompt correction of hypovolemic shock is the primary goal of treatment. This rare case presents a 75-year-old male who presented to the emergency department because of abrupt and increasing abdominal pain after a meal. Laboratory data revealed elevated alanine aminotransferase, aspartate aminotransferase, and alpha-fetoprotein levels. Immediate computed tomography demonstrated a defect in the right ventral abdominal wall. The patient underwent an emergency exploratory laparotomy. Despite massive intra-abdominal adhesions, the identified source of bleeding was from the left lobe of the liver at the base of the lesser sac above the pancreas. There was a maximum effort to cease bleeding and minimize blood loss. An ensuing biopsy of the liver revealed HCC. After improving, the patient received instructions to follow up on an outpatient basis. Two months after surgery, the patient endorses no complications. The success outlined in this case highlights the essence of prompt action in an emergency, which delineates the significance of surgical experience in handling unorthodox patient presentations.
