Methods A case of thymic carcinoma combined with papillary carcinoma within the thyroid was reviewed, and the clinical pathological features, imaging characteristics, histological morphology, immunohistochemical expression, treatment and prognosis were analyzed in combination with the literature. Results Thymic carcinoma combined with papillary carcinoma within the thyroid. Immunohistochemical results: Thymic carcinoma showed positive staining for CD5, CD117, P40, and negative for CD56, CgA, Syn, TTF-1, TG, and EBER. Papillary thyroid carcinoma showed positive staining for CK19 and Galectin-3, and negative for CD56.
