A 58-year-old male patient was admitted to the hospital complaining of weight loss. Abdominal computerized tomographic (CT) scan disclosed a mass shadow in the left kidney. From the results of further examination, including drip infusion pyelography (DIP) and angiography, he was preoperatively diagnosed as having a left renal tumor. Left radical nephrectomy was performed on March 15, 1990. The lesion was histologically diagnosed as renal cell carcinoma (clear cell subtype, grade 2) confined by the renal capsule (stage 1). No distant metastases were detected. Interferon-α was administered every other day as adjuvant chemotherapy. After the patient experienced muscle pain in his thighs and shoulders after exercise on February 11, 1991, the serum creatine phosphokinase (CPK) level progressively increased up to 2,329 U/l. On the basis of the results of various examinations reflecting thyroid gland function, he was diagnosed as having primary hypothyroidism due to Hashimoto's disease. Thyroid function improved after administration of triiodothyronine and thyroxine. Interferon has been reported to influence thyroid function, and, in this case, interferon-α therapy may have induced the primary hypothyroidism associated with Hashimoto's disease.
