A REPORT OF TWO CASES AND REVIEW OF LITERATURE

Abstract

ABSTRACT The clinical, radiographic, gross, and histopathological characteristics of two cases of teratocarcinomas occurring unilaterally in the ovaries of a 9‐year‐old and a 2‐year‐old dog with diffuse metastasis are described. Tissues of all three primordial germ layers, with a histological resemblance to different organ systems, were observed in the primary as well as in the metastatic lesions. Differentiation varied from matured elements to unrecognizable anaplastic cells. These are the first reported cases of teratocarcinoma in the dog.
