It was also encountered coincidentally with another mass taking place between distal esophagus and cardia of stomach and metastatic foci in kidney. In histopathological examination, perianal localization of mass and metastatic foci on lung were diagnosed as hepatoid gland carcinoma while esophagogastric mass and metastatic foci in kidney were diagnosed as leiomyosarcoma. In immunohistochemical examination, Ki-67 marker gave positive reaction in nuclei of anaplastic hepatoid gland cells in spite of vimentin and α-smooth actin positivity were found in reserve cells of the tumor. But, there was only positive with actin marker in leiomyosarcoma. It is considered useful to share results of the two different concurrent tumor in same dog}, number={1}, publisher={Ankara University}
