title: [A case report of extensively calcified renal cell carcinoma].
abstract: A 73-year-old woman visited another hospital with complaints of occasional episodes of gross hematuria. A computed tomographic (CT) scan revealed extensive calcification in the left kidney, and she was referred to our hospital for further examinations. The physical examination was unremarkable other than mild back pain on her left side. Blood chemistry was normal. The CT scan revealed a mildly enhanced tumor of 6 cm in diameter accompanied by extensive calcification in the left kidney. Angiography revealed a hypovascular tumor in the left kidney. A left radical nephrectomy was carried out. Gross appearance of the specimen showed extensive calcification from the renal pelvic to the parenchyma of the lower pole of the left kidney. The histopathological diagnosis was renal cell carcinoma, alveolar type, mixed subtype, pT2pN0pM0.
