title: Liposarcoma of the thyroid gland mimicking retrosternal goiter.
abstract: Primary liposarcoma of the thyroid gland is extremely rare with only two previous reports in the literature. We report two further cases, both patients presenting with rapid airways compression. Patient 1 had clinical, radiographic, and biopsy appearances suggesting benign goiter. Patient 2 had a long-term history of benign goiter, a previous partial thyroidectomy, and more recent biopsies showing liposarcoma. The management of such rare conditions is always challenging.
