Multilocular cystic nephroma in a young adult: A case report and review of literature

Introduction: Multilocular cystic nephroma is an uncommon condition with only few cases described in the literature, although its benign nature is well-recognized.

Case presentation: We present a case of a 28-year-old male patient who presented with a right flank pain, imaging suspected a multicystic renal cell carcinoma. A radical nephrectomy was performed view the size of the cyst and the high tumor complexity, which histology confirmed the diagnosis of multilocular cystic nephroma.

Discussion: Multilocular cystic nephroma is a rare renal tumor with few reported cases, making preoperative differentiation from cystic renal cell carcinoma difficult and leading to nephrectomy as the preferred treatment.

Conclusion: Multilocular cystic nephroma is typically benign, the scarcity of diagnostic and therapeutic experience necessitates vigilant postoperative surveillance to ensure patient safety and optimal outcomes.
