Introduction:
Thyroid gland fibrosarcomas are extremely rare tumors, and only very few cases have been described in the literature. There are no set recommendations along with follow-ups regarding the treatment of these tumors. Moreover, the prognosis is poor with a very short life expectancy.
Case Report:
We present an 81-year-old patient who was suffering from increasing dysphagia and dysphonia related to a painless giant cervical mass, which presented with progressive growth for the preceding months. After a core needle biopsy with a suspicion of a solitary fibrous tumor, total excision of the tumor was successfully performed, and the pathology examination revealed a fibrosarcoma. Following surgery, radiotherapy was decided in the oncological multidisciplinary meeting; however, the patient refused it. There were neither new clinical symptoms nor tumor recurrence after an 18-month follow-up.
Conclusion:
Although it is a very rare tumor, primary fibrosarcoma of the thyroid gland should be kept in mind in the differential diagnosis of neck tumors.
