A 40-year-old woman underwent excision of the right parotid gland tumor in 1988. The pathological examination showed adenoid cystic carcinoma. In 1993 she underwent excision of a recurrent tumor on the right face and was referred to our department because of an incidental finding of left renal tumors. She underwent nephrectomy and was diagnosed with left renal metastasis on pathological examination. In 1997 computerized tomography demonstrated multiple metastases in the right kidney, liver, lungs and brain. She died of cancer in 1998. Secondary carcinoma of the kidney is usually identified at autopsy and represents a late and poor manifestation of primary disease when diagnosed during life. The present case is unique in its primary site, pathology and clinical course.
