Case Reports in Gastroenterology
|January 24, 2013
Summary
This case study details a rare, widespread angiosarcoma affecting multiple organs, including the gastrointestinal tract and liver. Despite extensive treatment, the patient succumbed to complications from disseminated disease.
Area of Science:
- Oncology
- Gastroenterology
- Pathology
Background:
- Angiosarcoma is a rare and aggressive vascular malignancy.
- Gastrointestinal involvement is exceptionally uncommon, presenting diagnostic challenges.
Observation:
- A 72-year-old male presented with melena and anemia.
- Endoscopy revealed gastric and duodenal nodules; biopsies were inconclusive.
- Imaging identified lesions in the spleen, liver, and vertebrae.
Findings:
- Diagnosis of angiosarcoma was confirmed via endoscopic ultrasound-guided biopsy and fine needle aspiration.
- The angiosarcoma extensively infiltrated the gastrointestinal tract, liver, spleen, pancreas, kidney, lung, vertebrae, and pleuroperitoneal membranes.
- Despite splenectomy, embolization, and surgical interventions, continuous gastrointestinal bleeding led to fatal hemorrhagic shock.
Implications:
- This case highlights the aggressive nature and diverse metastatic potential of angiosarcoma.
- It underscores the diagnostic difficulties and challenges in managing widespread gastrointestinal angiosarcoma.
- Early recognition and multimodal treatment strategies are crucial for improving outcomes in rare vascular tumors.

01:28Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

01:24Esophageal Varices-I: Introduction
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
01:27Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
