Area of Science:
- Oncology
- Pathology
Background:
- Leiomyosarcoma is a rare malignant mesenchymal tumor originating from smooth muscle.
- Primary thyroid leiomyosarcoma is exceptionally rare, with limited documented cases.
Observation:

- Ultrasound revealed a suspicious mass in the left thyroid lobe.
Findings:
- Left hemithyroidectomy confirmed the diagnosis of leiomyosarcoma.
- This case adds to the scarce literature on primary thyroid leiomyosarcoma.
Implications:
- Discusses current understanding and management strategies for this rare thyroid cancer.
- Emphasizes the importance of considering rare diagnoses in thyroid pathology.
