Simultaneous Metastasis from Cervical Cancer to the Kidney and Paraspinal Muscle: A Case Report

Metastases of squamous cell carcinoma of the cervix to atypical locations may occur in approximately 12% of patients diagnosed with distant metastases, with the kidney and paraspinal muscle as one of the rarest sites of spread. A 34-year-old woman with a diagnosis of squamous cell carcinoma of the cervix stage IIIB, treated with chemotherapy and radiation, presented 21 months after completion of therapy, with two sites of simultaneous metastases (kidney and paraspinal muscle). No other evidence of disease was noted. She underwent right nephrectomy and radiotherapy to the para-spinal mass. She did not accept chemotherapy. The patient then had progression of disease in the right nephrectomy bed and a new left renal lesion. The paraspinal lesion presents a partial response. The patient declined further chemotherapy and died five months after the relapse. Simultaneous metastases of squamous cell carcinoma of the cervix to the kidney and paraspinal region is a rare entity, and there is currently no standard recommendation for treatment.
