Canine deciduoma induced by intralumenal insertion of uterine grafts.
This report deals with evaluation of histological characteristics of the canine deciduoma induced by insertion of the uterine grafts as a biological stimulus. Autografts induced severe uterine cystic endometrial hyperplasia, and the grafts were organized by maternal endometrium. On the other hand, allografts induced more severe hyperplasia of the uterine endometrium with stronger inflammation than autografts. Almost all allografts became necrotic and lytic in the uterine lumen. These results suggest that uterine grafts could induce deciduoma and that the maternal endometrium, though under the functional corpora lutea, recognized the uterine grafts to be a stimulant and showed severe cystic endometrial hyperplasia.
