Laparoscopic resection of a juxtaglomerular cell tumor of the right kidney.
Juxtaglomerular cell tumor is an extremely rare neoplasm of the kidney that causes blood hypertension. A 45-year-old man with persistent hypertension was referred to our department because of a solid mass of unclear origin (kidney? colon?) located in the right mesorenal region that had been detected by Computed tomography (CT) scan, ultrasonography, and colonoscopy. Serum levels of renin, plasma renin activity (PRA), and aldosterone were all normal. Operatively, four 10/12-mm ports were placed, ultrasonography confirmed a well-encapsulated lesion of the kidney. Ultrasonic shears and cautery were used to resect the lesion, including 5 mm of free renal tissue. Postoperatively, a prompt normalization of blood pressure was observed. The pathological findings showed a juxtaglomerular cell tumor. The definitive diagnosis of juxtaglomerular cell tumor is made on the basis of laboratory findings, and imaging studies, Its definitive treatment is surgical excision which can be accomplished successfully with minimally invasive surgery.
