Abstract

Soumia Ayachi and Achouak Bachir

Introduction: Kidney cancer is relatively rare when compered to other malignancies. It accounts for approximately 3% of adult malignancies. The renal clear cell carcinoma (RCCC) is the most common. In 70% of cases the disease is confined to the kidney and surgical approaches are generally curative. One third of cases is discovered in metastatic stage (30% of cases), specially bone and lung metastases; however, other rare metastases sites have also been described.

Case report: We report a fascinating case of kidney cancer with thyroid metastases, discovered fortuitously during the surgical management of multinodular goitre; in a 54 years-old-woman with a history of nephrectomy 9 years ago for renal neoplasm.

Conclusion: Thyroid metastases of kidney cancer are uncommon, it´s important for the surgeon and the oncologist to be able to recognize and differentiate thyroid metastases from primary tumours. The diagnosis can be suspected if the patient has a thyroid tumour and a past history of kidney cancer. These tumours, on the whole, tend to behave more aggressively and in most cases the use of multimodal therapy is recommended.
