    This study reports a rare case of angiosarcoma in the terminal ileum, developing 8 years after radiation therapy for ovarian cancer. This finding suggests a potential link between therapeutic irradiation and angiosarcoma development in unusual locations.

    Area of Science:

    • Oncology
    • Vascular Surgery
    • Radiology

    Background:

    • Angiosarcoma is a rare malignancy arising from endothelial cells.
    • Therapeutic irradiation is a known risk factor for secondary malignancies.
    • Ovarian carcinoma treatment often involves pelvic irradiation.

    Observation:

    • A 66-year-old female developed angiosarcoma of the terminal ileum.
    • The angiosarcoma arose 8 years after receiving postoperative irradiation for ovarian carcinoma.
    • This represents the sixth reported case of angiosarcoma at a site of prior therapeutic irradiation.

    Findings:

    • The development of angiosarcoma in an unusual anatomical site (terminal ileum) following therapeutic irradiation suggests a potential cause-and-effect relationship.
    • This case adds to the limited literature on radiation-induced angiosarcomas.

  • The findings support the hypothesis that irradiation may directly cause angiosarcoma or indirectly through chronic tissue damage and repair.

    • Implications:

    • Radiation therapy may increase the risk of developing angiosarcomas, particularly in irradiated tissues.
    • Further research is warranted to elucidate the mechanisms underlying radiation-induced angiosarcoma.
    • Clinicians should maintain a high index of suspicion for secondary malignancies in patients with a history of therapeutic irradiation.
