Objectives: This cystic hamartoma of the renal pelvis is a very unfrequent benign tumor. We report one case emphasizing its histology and performed a bibliographic review.
Methods: Mid age female patient with the incidental diagnosis of a renal mass taking up the pelvis.
Results: A radical nephrectomy was performed with the pathologic report of cystic hamartoma of the renal pelvis.
Conclusions: It is a cystic renal tumor with well-defined histologic and immunohistochemical criteria, and it probably does not involve any danger for the patient's live.
