Abstract
|
|
|
|
Paraganglioma is an uncommon and slowly-growing benign neuro-endocrine tumor originating from the extra-adrenal paraganglia. The most common site of head and neck paraganglioma is the carotid body. Paraganglioma of thyroid gland is a rare disease, and is hard to diagnose preoperatively since the pathologic features are similar to thyroid neoplasm, especially to medullary carcinoma. Occasionally, multiple paragangliomas can be found in the body. To our knowledge, there are two cases of synchronous carotid body tumor with thyroid paraganglioma that have been reported to date. We report a case of 34-year-old female with carotid body paraganglioma synchronous with intra-thyroid paragangloma, which was misdiagnosed as papillary thyroid carcinoma in the preoperative evaluation. After the tumors were successfully excised, there were no signs of complications and the patient has survived the 2-year-follow-up period without recurrence.
