Metastasis of leiomyosarcoma to the neck is very rare. To our knowledge, metastasis to both the thyroid and parotid glands has not been reported.
We report a case of retroperitoneal leiomyosarcoma metastatic to the thyroid and parotid glands. A 60-year-old woman was referred to Kitano Hospital. She had been treated for retroperitoneal leiomyosarcoma 4 years previously, and metastasis to the lung and thigh had occurred 2 years later. Metastatic lesions in the bilateral lobes of the thyroid gland and right parotid gland were treated by surgery, mainly to prevent the airway from narrowing as a result of the thyroid lesion. After the operation, she developed recurrence in the abdominal region and she was treated in other hospital. Recurrence of the thyroid lesion was not seen until her death 9 months after the operation.
Key words :metastasis, leiomyosarcoma, thyroid gland, parotid gland
