| Abstract |
|
Papillary renal cell carcinoma (PRCC), a histological subtype of renal cell carcinoma (RCC), accounts for approximately 10% of all RCC. Here, we report a case of metastatic RCC diagnosed unexpectedly in a 31-year-old female patient. Computed tomography revealed a renal abscess in the left kidney and the urine culture confirmed Escherichia coli producing extended-spectrum beta-lactamase. Despite appropriate antibiotic treatment for 2 months, the patient’s symptoms and radiological findings worsened and she underwent nephrectomy. Pathological examination confirmed type 2 PRCC and a further staging study found stage 4 (T3N1M1). Our findings indicate that malignancy should be considered in young patients with a bacteriologically confirmed urinary tract infection. |
