Unresectable Retiform Hemangioendothelioma Treated with External Beam Radiation Therapy and Chemotherapy: A Case Report and Review of the Literature

الملخص EN

Retiform hemangioendothelioma (RH) is an infrequently encountered vascular neoplasm of intermediate or borderline malignancy.

Treatment of RH is controversial.

We present a case of a 44-year-old Asian male presenting with an unresectable RH of the pelvis.

The patient was treated with concurrent low-dose Cisplatin and External beam Radiation (4140cGy in 180cGy per fraction).

This is the first report of a clinical complete response and a long-term local control of this rare tumor.

This has significant clinical implication, since it gives the first evidence of treatment of this rare tumor using concurrent low-dose chemotherapy and radiation.
