Renal Cell Carcinoma in Children: About Two Case Report

Introduction Renal cell carcinoma (RCC) is extremely rare in children. Several factors could influence prognosis, including stage, grade, histology, symptomatic presentation, and performance status. Among these, tumor stage is the most important predictor of disease prognosis for RCC. We report our experience with two cases of children with renal cell carcinoma in children. Cases Case 1: A 13-year-old girl presented macroscopic hematuria after a right lumbar trauma. The renal ultrasonography and CT urography showed a very limited rounding medio renal mass. Fine needle renal aspiration objectified RCC. Patient underwent transabdominal radical nephrectomy. Histopathology revealed RCC grade 2 of Furhrman T1b N0 M0. The postoperative course was uneventful. Case 2: A 9-year-old girl presented macroscopic hematuria. The renal ultrasonography showed a horseshoe left kidney with limited rounding mass. CT urography showed limited left renal mass of 31 × 25 mm. Fine needle renal aspiration objectified RCC. Patient underwent transabdominal radical nephrectomy with regional lymphadenectomy. Histopathology revealed RCC associated with translocation Xp11.2 grade 2 of Furhrman T1a N1M0. The postoperative course was uneventful. Conclusion RCC is rare in children but in children older than 5 years with renal masses it is very important to suspect diagnosis. Surgery is the best treatment and prognosis is favorable when the tumor is localized and completely eradicated.
