Microscopic features of the tumor a Testicular tumor composed of trabecles, small tubules and cords of polygonal mildly pleomorphic cells with abundant eosinophilic cytoplasm embedded in myxoid stroma with scattered granulocytes. Additionally, prominent area of ossification is visible. b Low (2%) proliferative index of tumor cells with Ki-67 antibody. c Strong cytoplasmic immunoreactivity of alpha inhibin in tumor cells (shown). The tumor had also strong immunoreactivity for S-100 protein
