[Renal cell carcinoma associated with circumferential "ring-like" calcification].
A 37-year-old man was found to have large calcification in the left kidney in a health check. This calcification has not changed in size during 3 years with computerized tomographic (CT) studies. However, a suspicious lesion for a malignant tumor with the calcification was suggested by a magnetic resonance image (MRI) study. Thus, the patient underwent tumor enucleation and the histology showed the mixed typed renal cell carcinoma. Although it remains controversial, partial nephrectomy or tumor enucleation would be considered in a case of renal cell carcinoma with calcification, which is usually considered to have a favorable prognosis compared to that of a tumor without a calcification.
