Abstract
A 70-year-old male presented with left flank pain and history of gross, total painless haematuria of 6 months duration. Investigations revealed a large solid and cystic mass suggestive of renal cell carcinoma in left kidney with possible infiltration of left psoas muscle. Histology of radical nephrectomy showed angiomyolipoma with multiple cysts lined by columnar epithelium suggestive of tuberous sclerosis and focal area of xanthogranulomatous pyelonepheritis. The rare combination of such lesions leading to diagnostic dilemma has not been reported in medical literature to the best of our knowledge.
