Juxtaglomerular cell tumour, abbreviated JCT, is a rare kidney tumour associated with hypertension and typically seen in adolescents or young adults.
It is also known as juxtaglomerular tumour and reninoma.[1]

- Increased aldosterone.
- Causes hypokalemia.
- Increased plasma renin.
Microscopic
Features:[3]
- Polygonal cells.
- Abundant granular, eosinophilic cytoplasm.[4]
- Perinuclear halo.
DDx:[2]
- Metanephric adenoma.
