A case report of renal inflammatory myofibroblastic tumor and renomedullary interstitial cell tumor / 中华泌尿外科杂志

ABSTRACT

Inflammatory myofibroblastic tumor (IMT)is a potentially or low-grade malignant mesenchymal neoplasm, which is rare in clinic. Renomedullary interstitial cell tumor(RICT) is a clinically rare benign renal tumor. The combination of these two diseases in one patient has not been reported. A 25-year-old female patient was admitted to the hospital due to left back pain for 12 days and hematuria for 1 week. MRI of kidneys showed a mass in the left renal pelvis, which was considered as renal pelvic carcinoma. Urine cytopathological examination was negative. Robot-assisted laparoscopic radical left nephroureterectomy was performed. There was no tumor recurrence or metastasis during the follow-up for more than 6 months after operation.
