A patient with a juxtaglomerular cell tumor with histological vascular invasion

Juxtaglomerular cell tumors usually occur during adolescence and early adulthood and are generally deemed benign. Beaudoin et al. report the case of a 51-year-old woman with a juxtaglomerular cell tumor of large size (9.8 cm versus the usual 2–3 cm), which showed histological signs of vascular invasion. Although no other evidence of malignancy was found, this case suggests that adult patients with large juxtaglomerular cell tumors should undergo follow-up after nephrectomy to enable detection of tumor recurrence and metastasis.
