Post-radiotherapy cutaneous angiosarcoma can develop in the breast years after treatment. This rare cancer requires vigilance for any new skin lesions in irradiated areas, as early detection is key for management.

Area of Science:

  • Oncology
  • Dermatology
  • Radiotherapy

Background:

  • Cutaneous angiosarcoma is a rare malignancy that can arise in previously irradiated skin.
  • Breast cancer patients treated with radiotherapy are at risk for developing secondary malignancies.

Observation:

  • A 44-year-old female presented with a violaceous, indurated plaque on her right breast 6 years after treatment for ductal carcinoma.
  • Histopathology revealed angiomatous proliferation consistent with angiosarcoma, confirmed after surgical excision and mastectomy.

Findings:

  • The patient developed recurrent angiosarcoma at the mastectomy scar site 2 years after initial treatment.
  • The latency period of 5-10 years post-radiotherapy for this complication underscores the importance of long-term surveillance.

Implications:

  • Clinicians should maintain a high index of suspicion for cutaneous angiosarcoma in patients with a history of radiotherapy, especially those presenting with unusual skin lesions.
  • Prompt diagnosis and multimodal treatment, including surgery and chemotherapy (e.g., paclitaxel), are crucial for managing this aggressive cancer.
  • Long-term follow-up is essential due to the potential for recurrence and metastasis.
