Introduction: Thyroid like Follicular Carcinoma of Kidney (TLFCK) is a rare kidney tumor composed of tightly packed follicle-like cysts filled with eosinophilic colloid like material and lined by cuboidal cells with scant cytoplasm and oval to round nuclei. Very few cases of thyroid like follicular carcinoma of kidney have been reported till now. We report a rare case of primary thyroid like follicular carcinoma of kidney. Case Report: A 60-year-old woman presented with right flank pain since last 2 months along with complaints of weakness, breathlessness and weight loss. CECT showed a well-defined hyperdense lesion in lower pole of right kidney. Patient underwent radical nephrectomy of right side. The renal lesion was diagnosed as thyroid like follicular carcinoma of kidney which was confirmed by immunohistochemistry. Conclusion: Thyroid like follicular carcinoma of kidney is a rare tumor with minimal symptoms, sometimes detected incidentally and with good prognosis. There are occasional reports of distant metastasis or recurrence. First line of treatment is radical nephrectomy followed by radiotherapy.
