Conclusion:
In conclusion, anaplastic thyroid carcinoma is an extremely aggressive
form of thyroid cancer that can present with atypical clinical
manifestations, leading to misdiagnosis. In this case report, we
highlight a rare case of anaplastic thyroid carcinoma mimicking cervical
tuberculosis, which underscores the importance of considering uncommon
etiologies in the differential diagnosis of necrotic neck masses. Given
the poor prognosis of these tumors, such an atypical presentation should
not delay the diagnostic and, especially, therapeutic management of such
aggressive cancers.
