UNILATERAL RENAL HYPERTENSION DUE TO ANGIOMATOUS TUMOR OF JUXTAGLOMERULAR CELL ORIGIN

A 22-year-old woman with hypertension and hypokalemia due to a juxtaglomerular cell tumor.

Secondary hypertension is responsible for less than 10% of cases of hypertension. If associated with hypokalemia, it may be due to primary or secondary hyperaldostronism, the latter being rarely caused by renin-secreting tumors. We present a 22-year-old woman with a history of hypertension and repeated hypokalemia, who was finally diagnosed with a small renin-secreting tumor after extensive par...

Congenital hypertension due to unilateral renal vein thrombosis.

A boy was found on the day of birth to have hypertension and radiological evidence of calcification of the left renal vein. Persistent hypokalaemia and hyper-reninaemia in the presence of a small left kidney and normal right kidney led to the decision to perform a left nephrectomy. The biopsied specimen showed old calcified renal vein thrombosis with accompanying medullary necrosis. Postoperati...

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....
