Metastasis of Renal Cell Carcinoma (RCC)

This case was of a 41 Year Female Patient who reported with a complaint of painful swelling over the left side of the lower half of the face.

There was no relevant medical history, but the past surgical history revealed that patient had undergone Nephrectomy one and half years before for RENAL CELL CARCINOMA (RCC). Recently she presented with swelling at the left frontal region with a progressive increase in pain. Physical examination by Dr. Mathan revealed a left frontal mass with normal overlying skin. Also, PET CT Scan revealed evidence of Metastatic Deposits over the left mandible towards the medial side and lesion extends to involve the skull base abutting the infra temporal fosse.

So patient was taken up for surgery with all pre-anaesthetic work up including COVID tests. Segmental Mandiblectomy with Infratemporal clearance and Pectoralis Major Myocutaneous Flap Reconstruction done. Composite resection with posterior maxillectomy and infra temporal clearance.

Conclusion

Besides, in most cases clinical behaviour of metastatic RCC is unpredictable. The signs and symptoms depend on the affected organ and the presence of metastatic deposits. Also, Metastasis of renal cell carcinoma to multiple sites is rare. Careful evaluation should be done to identify other metastatic sites and identify any metastatic deposits.
