Summary

Introduction

We present two cases of tumorlike lipomatous lesions in the thyroid cartilage. Both presented as circumscribed tumors by ultrasonography and were identified accidentally.

Methods

Two tumorlike lesions were identified in two different patients. Additionally, computed tomography and magnetic resonance imaging scans of the laryngeal skeleton were performed. Surgery was performed in one patient, and the lesion was excised. Histopathology revealed fatty tissue with several foci of hematopoietic cells.

Conclusion

This is the first report of intralaminar tumorlike lipomatous lesions in the thyroid cartilage. These should be included in the differential diagnoses of primary cartilaginous lesions of the laryngeal skeleton.
