Metástasis de carcinoma de células renales en localizaciones poco frecuentes: hipófisis, tiroides y mama. Revisión de nuestra experiencia y presentación de tres casos clínicos.

OBJECTIVE: Metastatic Renal Cell Carcinoma (RCC) may develop in different anatomical locations and after a strict follow up within normal limits. We assess the importance of close follow up in patients with history of RCC through 3 clinical cases with unusual locations of metastatic RCC. METHODS: We present 3 cases of metastatic involvement of pituitary, thyroid and mammary glands. We retrospectively review our data base on metastatic RCC with 76 patients. DISCUSSION: There is not agreement about the time of follow up and image methods requested after surgery of RCC. The reason is the development of late onset and atypical placement metastases. CONCLUSION: Metastatic disease of renal neoplasms can occur at any time and at any location. It is important to keep suspicion of metastatic renal disease in patients in this background, even in those with good progress and regardless of the years that have passed since the initial diagnosis.
