Clinically, hypertension, especially when severe or poorly controlled, combined with evidence of a kidney<unk>  via imaging or gross examination suggest a JCT. However, other kidney<unk> s can cause hypertension by secreting renin. JCTs have a variable appearance and have often being misdiagnosed as renal<unk>  carcinomas; dynamic computed tomography is helpful in the differential diagnosis. Post-operatively, the presence of renin granules in pathology specimens as well as immunohistochemical analyses could help differentiating this<unk>  from other primary renal<unk> s such as hemangiopericytoma, glomus<unk> , metanephric adenoma, epithelioid angiomyolipoma, Wilms<unk> , solitary fibrous<unk> , and some epithelial neoplasms.
