Follicular thyroid carcinoma(FTC)is the second most common form of thyroid malignancy,and it is associated with more aggressive growth and worse long-term survival outcomes relative to papillary thyroid carcinoma(PTC).Reliable approaches to preoperative FTC detection,however,remain to be established.Herein,a targeted Affibody-Au-Tripod nanoprobe was developed and successfully utilized to facilitate the targeted photoacoustic imaging(PAI)of epidermal growth factor receptor(EGFR)-positive cells and tumors.These Affibody-Au-Tripods were found to be highly sensitive and specific for cells expressing EGFR when used as a PA contrast agent in vitro,and studies conducted in an FTC-133 subcutaneous tumor model system in mice further revealed that these Affibody-Au-Tripods were able to specifically target these EGFR-expressing tumors while providing a strong photoacoustic signal in vivo.Importantly,these nanoprobes exhibited negligible cytotoxicity and robust chemical and physical stability,making Affibody-Au-Tripods promising candidates for targeted PAI-based FTC diagnosis.In addition,these nanoprobes have the potential to facilitate the individualized treatment of patients harboring EGFRpositive tumors. 展开更多

BACKGROUND Thyroid follicular renal cell carcinoma is a special type of renal cell carcinoma newly recognized in recent years.It has attracted attention because of its unique histology,immunophenotype,and clinical characteristics.It has a very low incidence,and the number of case reports available for review is limited.Moreover,a thyroid mass with type of tumour is rare.CASE SUMMARY We report a case of a renal mass with a bilateral thyroid mass that was accidentally discovered in a 60-year-old man during physical examination.B-mode ultrasound showed a hypoechoic mass in the middle and lower parenchyma of the right kidney,and computed tomography showed an iso-density shadow tumour in the right kidney.Contrast agents had a significant continuous enhancement effect on the tumour,and the enhancement was not uniform.After partial nephrectomy,pathological analysis was performed to rule out the possibility that the renal tumour was caused by thyroid tumour metastasis.Needle biopsy of the thyroid tumour confirmed that the renal cell carcinoma was not related to the thyroid tumour.The patient was alive at the last postoperative follow-up.CONCLUSION This is the third published case in which thyroid tumour biopsy was performed to confirm that thyroid follicular renal cell carcinoma is not thyroid related. 展开更多
