Summary
This study reports a rare case of leiomyosarcoma in a small axillary blood vessel. Despite wide local excision, the patient experienced recurrence and metastasis, highlighting the aggressive nature of these vascular tumors.
Area of Science:
- Vascular oncology
- Surgical pathology
- Malignant mesenchymal tumors
Background:
- Leiomyosarcomas are malignant tumors originating from smooth muscle cells.
- While commonly found in the inferior vena cava, leiomyosarcomas in smaller blood vessels are infrequently documented.
- This case highlights a rare occurrence in a peripheral blood vessel.
Observation:
- A 53-year-old male presented with a tumor in the right axilla.
- Surgical excision revealed a mesenchymal tumor within an axillary blood vessel.
- Electron microscopy confirmed the tumor cells exhibited characteristics of leiomyosarcoma.
Findings:
- The histopathology and electron microscopy confirmed a leiomyosarcoma of vascular origin.
- The patient declined adjuvant therapy following surgical management.
- The tumor demonstrated aggressive behavior with local recurrence and lung metastasis within 10 months.
Implications:
- This case underscores the importance of considering leiomyosarcoma in the differential diagnosis of vascular tumors, even in smaller peripheral vessels.
- The aggressive clinical course and rapid metastasis emphasize the need for vigilant follow-up and potentially novel therapeutic strategies for such rare malignancies.
- Further research into the specific biology and treatment of leiomyosarcomas in smaller blood vessels is warranted.
