Background: Renal cysts are common in clinical practice, but some may harbor rare pathological entities such as mixed epithelial and stromal tumors (MEST). Imaging studies are crucial for accurate diagnosis. While laparoscopic deroofing is an established approach for symptomatic renal cysts, encountering MEST within a cyst is uncommon.
Case Presentation: We present the case of a 37-year-old female who presented with persistent left flank pain. Imaging revealed a large renal cyst in the lower pole of the left kidney, classified as Bosniak 2. Despite analgesia, the patient’s symptoms persisted, leading to a laparoscopic deroofing procedure. Histopathological examination postprocedure revealed a MEST. The patient reported complete resolution of symptoms at the 3-month follow-up.
Conclusion: This unique case presents the successful identification and surgical management of a MEST masquerading as a lower pole renal cyst through laparoscopic deroofing. It also contributes to the existing literature by highlighting the importance of considering rare pathological entities in the evaluation of renal cysts and the value of laparoscopic techniques in their management.
