title: [Leiomyomatous renal cell carcinoma - case report].
abstract: According to WHO tumor classification histological subtypes of renal cell carcinoma are clear cell, papillary and chromophobe carcinoma. Carcinomas that do not fit readily into one of the categories should be assigned as unclassified. In recent literature new and emerging entities are described; follicular, clear cell papillary and cystic, oncocytic papillary and leiomyomatous renal cell carcinoma. The last one is microscopically composed of areas resembling clear cell carcinoma with sheets of epithelial cells having abundant clear cytoplasm and areas of mature smooth muscle. There are few articles describing above mentioned new entity. Altogether 14 cases are reported. In time of the diagnosis our patient had leiomyomatous renal cell carcinoma and metastatic tumors in both pulmonary lobes.
