Reninoma (juxtaglomerular cell tumor) is a rare cause of renin-mediated hypertension. We reported a 18 year old woman with history of hypertension for 3 years. Laboratory findings showed severe hypokalemia and markedly increased levels of renin and aldosterone. Kidney ultrasonography, abdominal computed tomography and magnetic resonance imaging revealed a small mass in the middle region of the right kidney. The patient underwent nephron-sparing surgery; immunohistochemical results demonstrated typical features of reninoma. Postoperatively, blood pressure and potassium levels were normal at 1 month follow-up.

Background: Juxtaglomerular (JG) cells are sensors that control blood pressure and fluid-electrolyte homeostasis. In response to a decrease in perfusion pressure or changes in the composition and/or volume of the extracellular fluid, JG cells release renin, which initiates an enzymatic cascade that culminates in the production of angiotensin II (Ang II), a potent vasoconstrictor that restores blood pressure and fluid homeostasis. In turn, Ang II exerts a negative feedback on renin release, thus preventing excess circulating renin and the development of hypertension.

Juxtaglomerular cell tumor (JxGCT) is a rare type of renal neoplasm demonstrating morphologic overlap with some mesenchymal tumors such as glomus tumor (GT) and solitary fibrous tumor (SFT). Its oncogenic drivers remain elusive, and only a few cases have been analyzed with modern molecular techniques. In prior studies, loss of chromosomes 9 and 11 appeared to be recurrent.

Renin is crucial for blood pressure regulation and electrolyte balance, and its expressing cells arise from Forkhead box D1-positive (Foxd1) stromal progenitors. However, factors guiding these progenitors toward renin-secreting cell fate remain unclear. Tcf21, a basic helix-loop-helix (bHLH) transcription factor, is essential in kidney development.

Juxtaglomerular cell tumors (JCT) are uncommon renin-secreting tumors of the kidney with cytologic findings of JCT rarely reported. We describe a case of JCT in a 37-year-old man with uncontrolled hypertension that was cured by removal of the tumor via partial nephrectomy. Cytology material was prepared by scraping of the freshly sectioned tumor mass and stained with Diff-Quik and Papanicolaou stains.

Article Synopsis
- Renin-expressing juxtaglomerular (JG) cells have a mechanism that senses pressure and regulates renin release based on changes in blood flow.
- The study investigates whether Piezo2 receptors, known for their role in detecting touch, play a role in controlling renin synthesis and release in JG cells.
- Results show that Piezo2 channels are not necessary for renin release or synthesis in JG cells under normal or stressed conditions, suggesting that other mechanisms need to be identified.
