METASTATIC RENAL TUMOR PRESENTING AS OVARIAN CLEAR-CELL CARCINOMA

Patients with clear cell adenocarcinoma of the kidney often present with metastatic disease, in some cases involving organs in which primary clear cell tumors occur. Under these circumstances, diagnosis of the renal primary tumor may be delayed. Herein we present a case of renal cell carcinoma metastatic to the ovaries initially treated as primary ovarian disease, until the appearance of other metastases prompted the discovery of its true origin. A high index of suspicion and the histologic characteristics of these tumors may allow earlier diagnosis and treatment of a renal primary tumor.
