A unique case report in a 63-year-old male: Thyroid-like renal carcinoma mimicking thyroid neoplasm.

INTRODUCTION AND SIGNIFICANCE

Thyroid-like follicular carcinoma of the kidney is an exceedingly rare neoplasm. Only a few cases have been reported in the literature. This tumor often presents with no specific symptoms and is frequently discovered incidentally during imaging studies. Diagnosis relies primarily on histological examination and the exclusion of thyroid markers.

CASE PRESENTATION

We present the case of a male patient who presented with flank pain and hematuria. A right renal mass was identified and subsequently underwent complete surgical resection. Histological analysis of the mass revealed Thyroid-like follicular carcinoma.

CLINICAL DISCUSSION

Despite its rarity, thyroid-like follicular carcinoma of the kidney should be considered in the differential diagnosis of renal lesions.

CONCLUSION

The low-grade malignancy and low metastatic potential associated with this tumor are encouraging factors. Further studies are necessary to better understand the pathogenesis of this rare neoplasm. Such knowledge is crucial for improving patient outcomes and investigating potential associations with conditions like hypertension.
