Resumen de Central Stellated Scar Sign:: Classic Imaging Finding of Renal Oncocytoma with Radiopathological Correlation
Juan Carlos González Matos, Juan Jesús Gómez Herrera, Pilar Ortega de La Obra
Oncocytomas are benign tumors, with the classic stellate scar found in up to a third of cases, mainly in large ones. We present the case of a 69-year-old man with a palpable, mobile, and painless mass on the right flank, where abdominal ultrasound and abdominal computed tomography detected the presence of a solid right kidney lesion with a central stellate area in the sinus.
Postoperative histological analysis confirmed the presence of oncocytoma with a central stellate scar. Biopsy may not be useful to distinguish this entity from renal carcinoma, surgery being necessary for definitive confirmation of the diagnosis of oncocytoma.
