ABSTRACT： ObjectiveTo analyze the ultrasonographic features of secondary squamous cellcarcinoma of the thyroid（SSCC-T）and evaluate the diagnostic value of ultrasound.MethodsAretrospective analysis was conductedon clinical and ultrasonographic data from 12 patients with pathologicall confimed SSCC-T treatedat BeijingFriendship Hospital，Capital MedicalUniversity between January 2O16and January 2O25.Evaluated parameters included lesion size，echogenicity，edge，vascularity，calcification，and cervical lymph node metastasis.Descriptive statistical analysis was performed to analyze the ultrasonographic features of SSCC-T，and Fisher'sexact test was conducted to analyze the correlation between different ultrasound clasifications and thyroid dysfunction.ResultsThe 12 patients showed the folowing ultrasound clasifications：nodular type 50.0% ，6/12），diffuse type （ 33.3%， 4/12） ， and mixed type（ 16.7% ，2/12） . All diffuse-type patients exhibited a characteristic cord-like hypoechoic pattern. Cervical lymph node metastasis was observed in all the patients，with 75.0% （9/12）showing lymph nodes >2 cmin maximum diameter.Thyroid dysfunction occurred in 66.7% （8/12） of patients，including 2 patients with dynamic shifts from hyperthyroidism to hypothyroidism.Diffuse and mixed types were associated with hypothyroidism（ P=0.038 ）.ConclusionsSSCC-T demonstrates specificultrasonographicfeatures，particularly thecord-likehypoechoicpatern in thediffse type.For patients with squamous cell carcinoma，regular ultrasound examinations of the thyroid and cervical lymph nodes combined withchanges inthyroid functionareconducivetothetimelydetectionof thyroid metastasis of squamous cell carcinoma.
