Synchronous primary ectopic intrathyroidal thymoma and papillary thyroid carcinoma: double trouble: a case report

Primary ectopic intrathyroidal thymomas are exceedingly rare, with only nine cases previously reported in the literature. Given the nonspecific clinical and radiological presentation, definitive diagnosis relies on pathological examination. Establishing the diagnosis might be challenging given the wide array of potential differential diagnoses. Accurate identification and exclusion of differential diagnoses are essential for appropriate patient management. The coexistence of primary ectopic intrathyroidal thymoma and papillary thyroid carcinoma appears to be incidental.
