A rare malignity observed in the appearance of angiomyolipoma; tubulocystic renal cell carcinoma after partial nephrectomy

Cystic neoplasms of the kidney are quite rare. Because they contain various differential diagnoses and their radiological features are not specific, their diagnosis is very difficult except for histopathological data. Usually, they can be confused radiologically with benign cysts of the kidney or angiomyolipoma. Radical or partial nephrectomy is the most commonly preferred curative treatment method when it shows features like rapidly growing or malignancy. Histopathological examination is required for definitive diagnosis. In this article, we aimed to present a rare case of tubulocystic renal cell carcinoma after partial nephrectomy in our clinic, who was followed up in another center for years with the pre-diagnosis of angiomyolipoma, in the light of the literature.
