초록
Intrathyroidal thymic carcinoma (ITC) is an extremely rare malignant tumor that presents a diagnostic challenge owing to its similarity to anaplastic thyroid cancer and other aggressive thyroid malignancies. We present the case of a 79-year-old woman who was initially suspected of having anaplastic thyroid cancer; however, post-operative pathology revealed an ITC. The patient underwent a palliative surgical approach consisting of right total thyroidectomy and selective neck dissection, followed by adjuvant radiotherapy and chemotherapy. Treatment was successfully completed without complications or relapse. This case serves as a reminder to consider ITC as a differential diagnosis in patients presenting with atypical features resembling anaplastic thyroid cancer and to approach the treatment plan with careful consideration of the individual patient’s age, tumor characteristics, and prognosis.

The patient underwent a palliative surgical approach consisting of right total thyroidectomy and selective neck dissection, followed by adjuvant radiotherapy and chemotherapy. Treatment was successfully completed without complications or relapse. This case serves as a reminder to consider ITC as a differential diagnosis in patients presenting with atypical features resembling anaplastic thyroid cancer and to approach the treatment plan with careful consideration of the individual patient’s age, tumor characteristics, and prognosis.
