“…3 Immunohistochemical study is not consistent, and there is no definite marker for CMN, but vimentin is always positive, SMA is sometimes positive, but in contrast to Wilm's tumor, WT-1 marker is always negative. 19 Another main differential diagnosis of CMN is clear cell sarcoma which is always SMA negative. There is no definite IHC marker for clear cell sarcoma.…”

“…However, tumor cells in rhabdoid tumor show characteristic cytoplasmic eosinophilic inclusions which are not seen in mesoblastic nephroma. [17][18][19] The best and only definite method of treatment of CMN is surgical removal of the tumor with and without preoperative or postoperative chemotherapy. Two of our cases showed recurrence and liver metastasis, both of which had good response to chemotherapy.…”

Background: Cellular mesoblastic nephroma is rare after infancy, and there are many controversial reports about its clinical presentation and treatment as well as outcome in infants, young children, and adolescents. Objectives: In this report, we will discuss our experience with four cases of cellular mesoblastic nephroma presented from infancy to childhood (from 18 months of age to 11 years of age). Cases: During 10 years, we had the experience of 4 cases of pediatric renal tumor with the diagnosis of cellular mesoblastic nephroma, which have been followed between 1 year and 6 years. There were three male and one female patients with the age of 1.5, 2, 2, and 11 years. These tumors showed variable characteristics according to the number of mitosis, proliferative rate, necrosis, immunohistochemical markers, and metastatic potential; however, despite of all of these variabilities, all of these patients have done well and all have been well at the end of study. Conclusion: Pediatric renal tumors with the histologic diagnosis of cellular mesoblastic nephroma have good outcome even with metastasis, mitosis, and high proliferative rate.
