Hypertension Due to a Renin-Secreting Juxtaglomerular Cell Tumor

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

Paraneoplastic secondary hypertension due to a renin-secreting desmoplastic small round cell tumor: A case report

Desmoplastic small round cell tumor (DSRCT) is a rare and aggressive malignancy with a poor outcome that occurs in adolescents and young adults; <200 cases of DSRCT have been reported. Renin-producing tumors are also rare and cases of extrarenal renin-producing tumors are even rarer. The present study describes the case of a 20-year-old male that was diagnosed with DSRCT and presented with seve...

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...

Renin-secreting tumor. Case report.

Renin-secreting tumor, though rare, should be considered in assessing severe hyperreninemic, hypertensive patients. We studied an 18-year-old girl with hypokalemic hyperreninemic hyperaldosteronism. No angiographic lesion could be detected. The plasma renin activity (PRA) of the right/left renal vein was 7.3. With a presumptive diagnosis of renin-secreting tumor (RST), the patient was operated ...

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 ...
