Solitary renal cysts are relatively common. The occurrence of transitional cell carcinoma (TCC) in a renal cyst is rare. We present the case of a 59-year-old man with a medical history of viral hepatitis B. During a workup for his hepatitis, a computed tomography scan revealed a large cystic tumour in the upper region of the left kidney. A radical left nephrectomy was performed. Microscopic examination of the cystic tumour revealed a grade 2 TCC. The cyst was lined by transitional epithelium. This is a case of a TCC growing within a renal calyceal cyst.

Abstract Microcystic transitional cell carcinoma is a rare variant of urothelial carcinoma; to date, it has been described only in the urinary bladder. We report 2 cases of microcystic transitional cell carcinoma arising in the renal pelvis. The first case occurred in a 73-year-old man with a history of superficially invasive transitional cell carcinoma who presented with macroscopic hematuria and anemia. The second case occurred in a 62-year-old woman who had no relevant medical history and presented with hematuria. Computed tomographic scan revealed a tumor of the renal pelvis. In both cases, microscopic examination showed invasive transitional cell carcinoma with prominent cystic features. The cysts were irregular in size and were deeply infiltrative. The cysts were lined by single or multiple layers of cuboidal or flattened cells with minimal cytological atypia. The first patient died of his disease 18 months after presentation. The second patient remained well at her 6-month follow-up examination. Microcystic transitional cell carcinoma is an unusual, deceptively bland variant of urothelial carcinoma, which can mimic benign lesions.

Employing the indirect immunoperoxidase technique, monoclonal antisera against blood group antigens A and B were used to localize the corresponding tissue isoantigens in normal ureter and transitional cell carcinoma of the ureter and renal pelvis in 29 patients. All five cases of normal ureters showed positive staining of tissue isoantigens within the transitional epithelium, and all twelve cases of noninvasive transitional cell carcinoma showed similar staining in tumor cells. Of the remaining twelve cases who had invasive tumor, eight lacked tissue isoantigens, while four cases exhibited positive staining. These results support the earlier findings that normal urothelium and noninvasive transitional cell carcinoma of the urinary tract possess ABO tissue isoantigens, while these isoantigens are most frequently absent in invasive tumors. In addition, this study also demonstrates that invasive transitional cell carcinoma of ureters and renal pelvis may continue to possess tissue isoantigens when studied by this sensitive, specific method.

Metastases from bladder transitional cell carcinoma (TCC) to the testis are very rare. These are usually found on autopsy and occur in advanced or metastatic bladder cancers. More common, known primary tumors that metastasize to the testis include prostate, lungs, melanoma, gastro-intestinal tract and the kidney. We report a rare case of solitary and synchronous metastatic TCC of the bladder to the testis, discovered on histological examination. This case illustrates that metastatic neoplasm to uncommon sites should be considered in the differential diagnosis for patients with a history of advanced bladder TCC.
