MACERATION OF FETUS IN THE JAPANESE SEROW (CAPRICORNIS-CRISPUS)

Out of 2,138 pregnant Japanese serows (Capricornis crispus), one case of the maceration of fetus was found in the winter of 1991, and examin ed pathologically. Because the fetus was covered with the hairs in the head and the neck regions, the fetus seemed to be implanted in the la st breeding season and retained. The endometrium lacked the placentome s completely and showed metaplasia to the keratinized or non-keratiniz ed squamous epithelium. In the non-keratinized region, the accumulatio n of neutrophils, eosinophils, lymphocytes, plasma cells and foreign g iant cells was prominent in the subepithelial connective tissue.
