Non-Wilms’ tumours account for less than 10% of the total primary renal neoplasm in childhood [1]. It is imperative to recognise non-Wilms’ tumour malignancy as the prognosis and management differs significantly. The differential diagnosis amongst others include the commonly misdiagnosed clear cell sarcoma and synovial sarcoma, a rare neoplasm for which only one case has been reported in literature till date. Despite advancements in immunohistochemistry (IHC), accurate characterisation often proves to be difficult and molecular studies are frequently required to arrive at the final diagnosis.
