Abstract
|
|
|
|
Papillary renal cell carcinomas (RCCs) can be classified into 2 subtypes (types 1 and 2), depending on their characteristic cytogenetics, immunostaining profiles, and gene-expression profiles. Compared with type 1 papillary RCCs, type 2 papillary RCCs are relatively rare and show more aggressive features. For those reasons, they are associated with a worse prognosis. A 13-year-old patient was admitted to the hospital with right kidney mass. A laparoscopic radical nephrectomy was performed, and results of the histopathologic examination confirmed it to be type 2 papillary RCC. Type 2 papillary RCCs are rarely found in unilateral and multifocal forms, especially in adolescence. Here, we report the unique case of papillary RCC at a young age.
