A Comprehensive Commentary on the Multilocular Cystic Renal Neoplasm of Low Malignant Potential: A Urologist’s Perspective. Cancers (Basel) 2022; 14:cancers14030831.

Abstract
Multilocular cystic renal neoplasm of low malignant potential (MCRNLMP) is a cystic renal tumor with indolent clinical behavior. In most of cases, it is an incidental finding during the examination of other health issues. The true incidence rate is estimated to be between 1.5% and 4% of all RCCs. These lesions are classified according to the Bosniak classification as Bosniak category III. There is a wide spectrum of diagnostic tools that can be utilized in the identification of this tumor, such as computed tomography (CT), magnetic resonance (MRI) or contrast-enhanced ultrasonography (CEUS). Management choices of these lesions range from conservative approaches, such as clinical follow-up, to surgery. Minimally invasive techniques (i.e., robotic surgery and laparoscopy) are preferred, with an emphasis on nephron sparing surgery, if clinically feasible.

Abstract
Multilocular cystic renal cell carcinoma (MCRCC), which exhibits low-stage and low-grade characteristics, is a special type of RCC. MCRCC is extremely rare and generally develops at ages >50 years. We herein report a case of MCRCC in a 28-year-old man, which, to the best of our knowledge, is the youngest case reported worldwide to date. The patient presented with irritative bladder symptoms for 1 year. Dynamic enhanced computed tomography (CT) imaging revealed a mass with inhomogeneous enhancement in the left kidney, with a rich blood supply. B-ultrasonography also revealed a renal protruding mass. As the mass was highly suspicious to be a malignant tumor, laparoscopic radical nephrectomy was performed and MCRCC was definitively diagnosed by pathological examination. The patient has been regularly followed up for 6 months, without complications or disease recurrence.
