[Cutaneous metastatic angiosarcoma of the forearm]

Summary
This case report details a rare cutaneous angiosarcoma on the forearm. Despite slow initial growth over 15 years, the tumor rapidly metastasized after resection, leading to patient death.
Area of Science:
- Oncology
- Dermatopathology
- Surgical Pathology
Background:
- Cutaneous angiosarcomas are rare vascular tumors, with a predilection for the head and neck, and exceptionally rare on the extremities.
- Limited data exists on the clinical and long-term behavior of angiosarcomas on the limbs.
Observation:
- A 57-year-old male presented with a large, exophytic, nodular left forearm tumor.
- Histological examination revealed a vasoformative pattern.
- Immunocytochemistry confirmed endothelial cell origin using anti-vWf, UEA I, and BMA 120 antibodies.
Findings:
- The patient's history indicated a slow-growing neoplasm for over 15 years.
- Following partial resection, the tumor exhibited rapid enlargement.
- The patient ultimately succumbed to widespread metastases.
Implications:
- This case highlights the aggressive potential of cutaneous angiosarcoma, even with a prolonged slow-growth phase.
- Early and complete resection may be crucial for improving outcomes in extremity angiosarcomas.
- Further research into the molecular drivers and prognostic factors of these rare tumors is warranted.
