title: Sigmoid colon angiosarcoma with intraperitoneal bleeding and early metastasis.
abstract: Angiosarcoma of the gastrointestinal tract is a very rare malignancy with only a few cases reported in the literature. The case of a 60-year-old woman who presented with abdominal pain and a sigmoid mass on computed tomography (CT) scan is reported. Upon exploration, the patient was found to have a subserosal hemorrhagic mass. Angiosarcoma of the sigmoid colon was diagnosed upon pathological examination. The patient developed subsequent recurrence of her disease with distant metastasis. Approximately 4 months later, she expired. Angiosarcoma of the gastrointestinal tract is a very aggressive malignant tumor. The primary treatment is surgical excision. The role of adjuvant therapy is not well established.
