Congenital mesoblastic nephroma.
Congenital mesoblastic nephrorna (CMN) is a rare lesion but in the neonatal age group is second only to sacroccygeal teratoma. It is thought to be variant of Wilms tumour that also arises from primitive renal cells. Molecular characterisation and pattern of gene expression suggests that different factors are involved in the pathogenesis of these two tumours. CMN is generally a benign tumour alt...
متن کاملNew look at mesoblastic nephroma.
Thirty eight mesoblastic nephromas were studied. The age range of the patients was between the neonatal period and 18 months. The presence of cartilage is consistent with a mesoblastic origin, but squamous epithelium was a feature in three tumours. Particular attention was given to the adjacent renal tissue in which various histological features were noted: vacuolated and dysplastic tubules; cy...
متن کاملPrenatal diagnosis of congenital mesoblastic nephroma
Congenital mesoblastic nephroma is a rare renal tumor that is diagnosed during pregnancy and is associated with polyhydramnios, prematurity, and neonatal hypertension. Differential diagnoses include Wilms tumor, adrenal neuroblastoma, and other abdominal tumors. We report a case of congenital mesoblastic nephroma detected by prenatal ultrasonography as a large fetal renal mass with polyhydramni...
متن کاملCellular congenital mesoblastic nephroma: case report.
INTRODUCTION Congenital Mesoblastic Nephroma (CMN) is a rare pediatric renal tumor. It comprises two histological subtypes, namely classic and cellular, with the second accounting for two thirds of all cases and being more often associated with poor prognosis. It remains a diagnostic challenge for pathologists due to its similarity with other more frequent pediatric kidney neoplasms. CASE REP...
متن کاملCellular Congenital Mesoblastic Nephroma in a Newborn
Typical nephroblastoma (Wilms'tumor) is uncommon within the first 6 months of life. Renal tumors most commonly found in this age constitute of two groups which have a better and worse prognosis, respectively, than typical nephroblastomas. The group of tumors with a better prognosis encompasses congenital mesoblastic nephroma (CMN), fetal rhabdomyomatous nephroblastoma and cystic, partially diff...
