A five-month-old male baby presented with an abdominal mass which was found on computerised tomography (CT) to be involving the left kidney. Nephrectomy and histopathological study showed morphological featues of a malignant rhabdoid tumour. The tumour cells stained strongly for cytokeratin and epithelial membrane antigen and less intensely for vimentin. Electron microscopy revealed concentric whorled arrays of intermediate filaments within the tumour cell cytoplasm. The child was put on post-operative chemotherapy and radiotherapy but developed bilateral lung metastases and died three months after surgery.
