Özet

Leiomyomas are rare, benign and solid tumors of the kidney. Although the developments in radiological imaging methods provide early detection of kidney tumors, it is difficult to differentiate leiomyomas radiologically from other malignant renal tumors. Moreover, the definitive diagnosis of leiomyomas can only be achieved by histopathological and also immunohistochemical evaluation after surgical intervention. Immunohistochemically, positive staining with smooth muscle actin and vimentin, whereas negative staining with cytokeratin, S100, Mart1 and HMB45 are the methods used in the differential diagnosis of leiomyomas.
