A cystadenoma or a cystadenocarcinoma arising from the renal pelvis is a rare neoplasma and, so far as is known, only two cases have been reported in the literature (Arcadi, 1956, and Ross, 1985). Discussed herein is a case of a 63-year-old woman who developed a mucinous nephrosis, due to a marked retention of mucin produced by a tumor. The ureter as well was found to be involved. The histogenesis of an adenocarcinoma, which includes a cystadenoma and a cystadenocarcinoma, most likely is due to a glandular metaplasia, associated with urolithiasis and pyelonephritis. In this specific case, the patient revealed a history, fifteen years earlier, of renal calculi and pyelonephritis.

A rare case of primary papillary adenocarcinoma of the renal pelvis is reported. A 75-year-old man was introduced to our institute because of chance hematuria. He had no history of urolithiasis or urinary tract infection. Excretory urography showed a space taking lesion at the lower position of left renal pelvis with low function. Because of advanced stage with paraaortic lymphnode invasion, simple nephrectomy followed by irradiation and systemic chemotherapy with 5-FU was done. He died of pneumonia and acute heart failure after subtotal gastrectomy for peptic ulcer four months after the nephrectomy. Excised specimen revealed papillary adenocarcinoma of the renal pelvis without mucin production. This case was the 51st case reported in the literature. A short review of the disease is also reported.

Mucinous cystadenoma with malignant transformation occupying the lower half portion of the right renal pelvis in a 69-year-old Japanese man was recorded. The patient had recent dysuria but no clinical history of pyelonephritis or urolithiasis. Under the clinical diagnosis of unusual renal cyst, the right total nephrectomy was performed. Grossly, the cystic tumor, 5 cm across, formed a monolocular lumen filled with mucins and showed no direct communication with the renal pelvis inside. Microscopically, the epithelial lining was characterized by a single layer of benign mucin producing columnar cells that scattered foci of non-invasive papillary projections with cell stratification and nuclear atypia suggestive of malignancy. Although there was non-specific chronic pyelitis, no pyelitis cystica et glandularis was encountered. Of circa 60 glandular neoplasms arising in the renal pelvis reported previously, adenomas are only five including two mucinous cystadenomas, while the remainder are adenocarcinomas. The histological findings of mucinous cystadenoma in the present case may represent the process of a transition from adenoma to adenocarcinoma. The result suggests the possibility that adenoma-carcinoma sequence may exist among the glandular neoplasma arising in the renal pelvis. The histogenesis was unclarified.
