Plain-English summary
A 16-year-old mare that had never given birth before lost a seemingly healthy foal after about 240 days of pregnancy. When the foal was examined, a large mass was found attached to its umbilical cord, measuring about 20 cm by 30 cm by 20 cm. This mass had various unusual features, including cysts, areas of bleeding, and different types of tissues like cartilage and muscle. The mass was identified as an umbilical cord teratoma, which is a very rare type of tumor. This case is notable because such tumors are extremely uncommon in both humans and animals.
Abstract
A 16-year-old primiparous mare aborted an apparently normal fetus at 240 days of gestation. A large, oval mass, measuring approximately 20 cm × 30 cm × 20 cm, was detected attached to the umbilical cord of the fetus. On the cut surface, the mass showed multifocal cystic structures, foci of mineralization, and diffuse hemorrhages. Histological examination of the mass revealed haphazardly arranged cartilage, bone, mesenchymal stroma, adipose tissue, vascular structures, smooth muscle, ciliated epithelium, squamous cornifying epithelium, and undifferentiated germ cells with areas of necrosis and mineralization. The mass was diagnosed as an umbilical cord teratoma, which is an extremely rare tumor in human beings and, to the authors' knowledge, has only described in the veterinary literature on one occasion.
