title: [Bellini duct carcinoma of the kidney: a case report].
abstract: We report a case of Bellini duct carcinoma. A 65-year-old man visited our hospital because of an asymptomatic right renal mass directed by ultrasonography and computed tomography in an other hospital. His urine cytology was negative. The tumor showed a minimal enhancement in computed tomography. Under the preoperative diagnosis of an atypical right renal tumor, laparoscopic right radical nephrectomy was performed. The tumor is 50 mm in diameter and the surface was grayish-white in color. The histopathological diagnosis was low-grade Bellini duct carcinoma. Immunohistostaining revealed positive staining for UA-1 and EMA in the tumor tissue. No evidence of recurrence or metastasis was noted 36 months after surgery without any adjuvant therapy.
