Case report Metastatic liposarcoma of the thyroid gland

Metastatic liposarcoma of the thyroid gland is exceptionally rare. A case of pleomorphic liposarcoma, which manifested as a soft tissue lump in the neck, is described in a 30-year-old woman. Fine needle aspiration cytology permitted prompt diagnosis. The ultrasound and CT appearance of this type of thyroid metastasis is described which has not been previously reported in the literature. The majority of soft tissue sarcomas metastasize to the lungs. Liposarcomas may have a different metastatic pattern, with a tendency to disseminate towards extra- pulmonary sites. We report the case of a 30-year-old woman with a known history of liposarcoma of the right thigh, pre- senting with a painless nodule in the right side of her neck, which was confirmed to be in the right thyroid lobe on imaging. An ultrasound-guided fine needle aspiration cytology (FNAC) was consistent with a diagnosis of metastatic liposarcoma.
