輪状石灰化内に認めた腎細胞癌の1例

Abstract

37歳男.全周を石灰化で覆われた腎細胞癌の1例.腎辺縁に位置し石灰化で完全に覆われた腎細胞癌の場合, 一部の症例においては, より侵襲の少ない腫瘍核出術が適応になりうると考えられた

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.
