## Abstract

This case report details a case of intrathyroid thymic carcinoma (ITTC). ITTC is extremely rare with few reports. Diagnosis is difficult due to a lack of specific features and depends on pathology. A 36‐year‐old male was diagnosed. His condition and relevant tests are described. The tumor was removed, and he recovered well. This case report also discusses ITTC's characteristics, diagnosis, treatment, and prognosis, emphasizing its rarity and the need for a better understanding.

This case report highlights the challenges in diagnosing intrathyroid thymic carcinoma (ITTC), a rare thyroid tumor, and underscores the importance of postoperative pathology for confirmation. The study emphasizes the good prognosis of ITTC with appropriate surgical management.
