Renin‑secreting juxtaglomerular cell tumor of the kidney causing severe hypertension and polyuria

Renin‑secreting juxtaglomerular cell tumor of the kidney causing severe hypertension and polyuria.

Juxtaglomerular cell tumor of the kidney: a case report.

We report a case of renin-secreting juxtaglomerular cell tumor which developed in a hypertensive 47-yr-old Korean man. Presumptive clinical diagnosis was made before surgery based on the high level of plasma renin and the radiologic evidence of renal mass. Grossly, a round, bulging, well-encapsulated mass of 3 x 3 cm was located in the mid-portion of the right kidney. On microscopic examination...

Nonfunctioning Juxtaglomerular Cell Tumor

The juxtaglomerular cell tumor (JGCT) is a rare renal tumor characterized by excessive renin secretion causing intractable hypertension and hypokalemia. However, asymptomatic nonfunctioning JGCT is extremely rare. Here, we report a case of nonfunctioning JGCT in a 31-year-old woman. The patient presented with a left renal tumor without hypertension or hypokalemia. Under a clinical diagnosis of ...

Anatomic Pathology / JUXTAGLOMERULAR CELL TUMOR

We studied 4 new cases of juxtaglomerular cell tumor and compared their morphologic and immunohistochemical features with 2 renal hemangiopericytomas and 5 cutaneous glomus tumors. The juxtaglomerular tumors were resected from 2 males and 2 females (mean age at diagnosis, 23 years). Three patients manifested with severe hypertension. Tumors ranged from 2.2 to 8.0 cm and were well circumscribed....

A Case of Juxtaglomerular Cell Tumor of the Kidney Treated with Retroperitoneal Laparoscopy Partial Nephrectomy

An abdominal computed tomography scan showed a 3‐cm isodensity and weak contrast‐enhancing but delay‐enhancement solid mass in the right kidney cortex [Figure 1a and 1b]. Renal Doppler was also ordered which revealed normal renal vessels with normal flow pattern. An ultrasonography confirmed a well‐defined rounded and hypoechoic solid mass at the same location. Selective renal arteriography sho...
