title: A case of renal cell carcinoma found after skin metastasis.
abstract: A case of renal cell carcinoma, found after skin metastasis is presented. A 79-year-old man visited Osaka JR hospital, complaining of a painless nodular mass on his right chest. The mass was resected and histopathological examination revealed a clear cell carcinoma (alveolar type, G1) with no involvement of the mammary gland. Abdominal ultrasound and magnetic resonance imaging revealed a heterogenous lower pole mass in the right kidney. Ultrasound-guided needle biopsy of the right renal mass was performed for histopathological diagnosis, which was clear cell carcinoma (alveolar type, G1). At that time, multiple metastases appeared in bilateral lung fields. The patient is currently receiving interferon-alpha therapy, without surgical treatment.
