A Case of Renal Cell Carcinoma Metastatic to the Right Zygoma

Abstract

Cutaneous metastasis from renal cell carcinoma is not unusual, occurring in 3 to 7%, although it may be overlooked. We report a case of metastatic renal cell carcinoma in a 74-year-old man who was presented with a 1.5 x 1.5 x 0.5 cm-sized nodule on the right zygoma for 3 months. A skin biopsy demonstrated the typical clear cell adenocarcinoma with PAS(+) granules in the cytoplasm and honeycombed or glandular configuration, compatible with metastatic renal cell carcinoma. Kidney ultrasonogram and abdomina1 CT scanning showed a large cystic mass on the upper pole of the left kidney. Furthermore radiologic studies revealed multiple metastatic lesions in the lung, liver and brain. He died 4 months later.
