Cystic Partially Differentiated Nephroblastoma (CPDN): A Rare Variant of Wilms' Tumor
Abstract
Cystic partially differentiated nephroblastoma (CPDN) is a rare variant of Wilms' tumor (nephroblastoma). It is an unusual neoplasm with a well-differentiated cystic lesion of the kidney. We herein report a case of a 4 month old boy presented with abdominal distension and left flank mass. Abdominal radiograms showed soft tissue haziness in the left side of the abdomen with no calcification. Abdominal ultrasonograms revealed a large multiseptated cystic mass involving most of the left kidney. CT scan of the abdomen showed a 6X7 cm hypodensed mass with well-defined septa of the left kidney. There was no extension of the tumor to the renal capsule and the lymph nodes showed reactive changes. Left nephrectomy was performed. The pathological diagnosis was cystic partially differentiated nephroblastoma (CPDN). Post-operative course was uneventful and the patient has been doing well since.
