Adenocarcinoma in multilocular renal cyst

Multilocular cystic renal adenocarcinoma: A case report and review of the literature

“…Cytology and chemical analysis of the cyst aspirate may give some useful information. Sadlowski et a1 [9] observed elevated LDH VA ratio in chemical analysis of cyst fluid. Its cytology was, however, negative for malignancy in their case [9] as well as in ours.…”

“…Sadlowski et a1 [9] observed elevated LDH VA ratio in chemical analysis of cyst fluid. Its cytology was, however, negative for malignancy in their case [9] as well as in ours. Although surgical exploration might be available to all renal masses, even frozen section might not always be valuable for accurate diagnosis, because of small and focal malignant areas.…”

Actual Approach to Cystic Nephroma

“…Nevertheless some of these criteria will have to be adated because recently 3 bilateral cystic nephromas have been reported [2,13,14] and reports of cystic ne phroma with a Wilms' tumor in the remaining kidney have been published [2,3,15], The reports of renal ade nocarcinoma found in cystic nephroma [2,16,17] are probably adenocarcinoma with cystic degeneration due to tumor necrosis and/or hemorrhage. Cystic nephroma, certainly in the adult, is a benign neoplastic lesion of the kidney originating in the metanephrogenic tissue, out of which the functional renal parenchyma normally develops.…”
