Radiation-induced cutaneous angiosarcoma of the abdomen in a patient with cervical cancer: A case report.

Cutaneous angiosarcoma (CA) is a rare and aggressive malignant tumor that develops from vascular endothelium. Secondary CAs are often caused by radiotherapy and chronic lymphedema. Most radiation-induced CAs are associated with breast or gynecologic cancer. The prognosis of CA is extremely poor, with a 5-year survival rate ranging from 12% to 34%. Therapeutic options are limited, and surgical excision with negative margins remains the mainstay of treatment. We report a case of a 63-year-old woman who developed secondary CA at an irradiated site 7 years after receiving radiotherapy for cervical cancer.
