“…In recent years, in addition to the lungs, IMT has also been reported in extrapulmonary tissues, including the head and neck, ventricles, liver, retroperitoneum, pelvis, and spinal canal[1-9]. In the genitourinary system, IMT was found to occur in the bladder, ureter, urachal, renal pelvis, and kidney[11-15] . Although most commonly found in the bladder[10], IMT in the kidney is extremely rare.…”

“…For patients with only one kidney, bilateral masses, or kidney insufficiency, a biopsy and intraoperative rapid pathological examination were strongly advocated by some authors because of the advantages in excluding malignant tumors and avoiding unnecessary removal[14]. But these approaches are still controversial, as the correct diagnosis is usually made only after nephrectomy[15]. Fortunately, with the widespread application of partial nephrectomy, the function of kidneys are saved gradually.…”

BACKGROUNDInflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor that is characterized by spindle cells differentiated from muscle fibroblasts and infiltration of various types of inflammatory cells. IMT can occur at any age and at any anatomic site. The most common location of IMT is the bladder in the genitourinary tract. Only scarce cases of kidney IMT have been reported in the literature.CASE SUMMARYA 77-year-old woman, with a history of bilateral renal calculus for 15 years, was admitted to the Department of Urology of our hospital complaining of recurrent painless gross hematuria for one month. The treatment with cephalosporin was ineffective. Computed tomography imaging showed a mixed density and slightly heterogeneously enhanced lesion in the middle pole of the left kidney and ipsilateral adrenal enlargement. The patient underwent surgical treatment by retroperitoneoscopic left radical nephrectomy plus adrenalectomy. A large number of typical spindle cells surrounded by plasma cells and lymphocytes were observed microscopically. Immunohistochemical analyses indicated that these spindle cells were positive for vimentin, cytokeratin (CK), Ki-67, CK7, CD34, and CD31 and were focally positive for CD10 and anaplastic lymphoma kinase (ALK-1). Thus, a diagnosis of IMT was made definitively. The patient recovered well after operation, and no recurrence or metastasis was noted during the 22-mo follow-up.CONCLUSIONSince kidney IMT is very rare and lacks characteristic clinical manifestation, it is easily misdiagnosed as a malignant tumor before operation. Surgery remains the best choice for diagnosis and treatment, and such cases must be followed carefully because of the uncertain biological behavior of this tumor. This report suggests that renal calculus may be one of the causes of IMT, but further investigation is necessary to prove it.

“…It was decided to obtain a CT guided biopsy of the mass, which showed adipose tissue with cytologic atypia and inflammation. A MRI was also performed but this did not allow a definitive diagnosis, with findings compatible with a range of entity, from angiomyolipoma to liposarcoma to renal cell carcinoma ( 1 – 4 ) ( Figure-2 ). Therefore, surgical options were discussed with patient.…”
