With a median diagnosis of two months and over 90% of cases occurring within the first year of life, it is the most prevalent non-Wilms’ renal tumour. Even though imaging can be used as a diagnosing tool, it is frequently identified in the neonatal period when the baby has an abdominal mass. There are three different histologic types: mixed, cellular, and classic. Radical nephrectomy is the usual mode of treatment, though adjuvant chemotherapy may be necessary for the cellular type, which may be aggressive. Case presentation: We report on a case of a 2-day-old term male neonate born to a 27-year-old mother through spontaneous vertex delivery (SVD). He presented with a right-sided abdominal mass from birth. An abdominal ultrasound scan revealed a huge, well-circumscribed heterogeneous soft tissue mass in the right hemi-abdomen extending to the left side, measuring 10.2 cm by 8.0 cm. He underwent a right radical nephrectomy with a tumour weight of 450 g and a size of 18 cm × 15 cm × 6 cm. Histopathological diagnosis was Congenital Mesoblastic Nephroma (cellular type) Stage 1. Conclusion: Any infant with a renal tumour should be evaluated for congenital mesoblastic nephroma. Detailed investigation and complete resection are fundamental for ensuring an excellent outcome.展开更多
