A rare case of primary mucinous adenocarcinoma of the renal pelvis is reported. A 76-year-old woman was admitted to our hospital because of right abdominal fullness. Physical examination revealed a melon-sized (22 cm in diameter) tumor located in the middle and lower right quadrant of the abdomen. Computed tomography and transabdominal sonography revealed hydronephrosis and a renal stone. Retrograde pyelography was impossible because of ureteral obstruction on the right side. A diagnosis of severe hydronephrosis was made and a right nephrectomy was performed. The kidney measured 24 x 14 cm in size and contained 1, 500 ml of mucinous material. The histological diagnosis was mucinous adenocarcinoma of the renal pelvis. The patient has had neither recurrence nor metastasis for 2 years following postoperative chemotherapy.
