ABSTRACT
The acquired cystic disease of the kidney-associated renal cell carcinoma (ACDK-RCC) in the current study occurred in a kidney with multiple cysts and was composed of cells with eosinophilic cytoplasm and prominent nucleoli. There were extensive calcium oxalate deposits in both non-neoplastic cysts and tumor. The tumor cells were positive for RCC Ma, CD10, and EMA, focally positive for CK7, negative for vimentin. Interphase in situ hybridizations (FISH) were performed for chromosome 1, 2, 7, 10, 13 and 17. No chromosomal abnormality was observed in the non-neoplastic cysts. Polysomies of chromosomes 1, 2, 7, 10, 13, 17 were observed in the tumor. Trisomy 13 was first reported in this type of tumor, which warranted further study.
