Thyroid malignancies are one of the fastest growing cancers in the world, with the majority being papillary thyroid cancer. Follicular variant of papillary thyroid cancer accounts for about 10%-20% of papillary thyroid carcinomas. The usual sites for metastases of these tumours are lungs and bones with renal metastases being extremely rare. We describe a case of a 64-year-old woman who presented with abdominal pain. On subsequent imaging, she was found to have a colonic mass with metastatic lesions in the lungs and tumour involving left kidney. On biopsy and immunohistochemical staining, the renal mass showed positivity for thyroid cancer markers. Thyroid scan was noted to be negative and the patient was placed on active surveillance after undergoing chemotherapy for colonic adenocarcinoma.
