Summary
This case report details a rare instance of metastatic leiomyosarcoma appearing as multiple breast masses. It highlights the unusual occurrence of leiomyosarcoma with an unknown primary origin metastasizing to both breasts.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Leiomyosarcoma is a rare soft tissue sarcoma.
- Metastasis to the breast is uncommon, especially from an unknown primary.
- Bilateral and multifocal breast disease presents diagnostic challenges.
Observation:
- A patient presented with bilateral, multifocal breast masses.
- Imaging and biopsy confirmed metastatic leiomyosarcoma.
Findings:
- This case represents a rare convergence of three uncommon entities: leiomyosarcoma of unknown primary origin, breast metastases, and bilateral, multicentric breast disease.
- The presentation mimicked primary breast cancer, underscoring the need for thorough differential diagnosis.
Implications:
- This case expands the understanding of leiomyosarcoma's metastatic potential.
- It emphasizes the importance of considering rare diagnoses in breast imaging and pathology.
- Accurate diagnosis is crucial for appropriate patient management and treatment planning.
