Background. Quite rare benign kidney lesions include leiomyoma, hemangioma, lipoma, juxtaglomerular cell tumor. Since most benign lesions of the kidney do not manifest themselves, they are usually confirmed by chance during histological examination of the material after surgical treatment.
Description of the clinical cases. 3 patients with rare benign kidney tumors were operated at the City Clinical Hospital № 52 from 2022 to 2023. Two patients underwent laparoscopic resection of a kidney with a tumor, one patient - laparoscopic nephroureterectomy with resection of the bladder orifice. All patients underwent minimally invasive surgical treatment. There was no bleeding or death. According to histological and immunohistochemical examinations, rare benign kidney formations were revealed: mixed epithelial stromal tumors of the kidneys, kidney leiomyoma, anastomosing kidney hemangioma.
Conclusion. Reporting new cases of rare subtypes of benign kidney lesions has important clinical and scientific value in order to develop optimal approaches to the diagnosis and treatment of both benign and malignant kidney tumors.

Keywords: mixed epithelial stromal tumors of the kidneys, mesenchymal tumor, hemangioma, kidney tumor, leiomyoma
