Abstract
Papillary renal carcinoma (papillary RCC) is a histological subtype of the renal carcinoma, which in turn, has two morphological subtypes that correlate with prognosis. The present study reported an unexpected finding of type 2 papillary renal cell carcinoma (papillary RCC) presenting intracystic necrosis cavity. A cystic renal lesion was identified incidentally in a 66‑year‑old man during an abdominal computed tomography (CT) scan performed for the evaluation of a gastrointestinal stromal tumor. Subsequent contrast material‑enhanced CT scan and magnetic resonance imaging (MRI) examination labeled the mass as category Ⅲ degree on the basis of the Bosniak classification scheme. Surgical exploration by laparoscopic radical nephrectomy was performed to determine the diagnosis. Definitive pathological study confirmed a type 2 papillary RCC with an intracystic necrosis cavity. To the best of our knowledge, this case demonstrated for the first time a cavity within a papillary RCC, supporting the hypothesis that type 2 papillary RCC could develop cavity avascular necrosis during its cystic degeneration.
