Abstract: A case of canine testicular disseminated malignant seminoma is reported. An 8-year-old male dog showed that the testis increased fast. Histopathological examination found masses of tumor cells derived from the germ cells that constitute the spermatogenic epithelium within the seminiferous tubules. Those tumor cells are in the similar shape forming broad sheets. These findings were con- sistent with all disseminated malignant seminoma.
