Abstract:
Herein, we describe a case of uterine calcification in the uterus of a pig without pregnancy loss. The recipient underwent cloned embryo transfer and Cesarean section for safe delivery of cloned piglets. During the Cesarean section, 4 white, star-like, (2 × 2 × 2) cm, calcified structures were found within the endometrial cavity. Despite dystrophic calcification around the placenta, healthy cloned piglets were produced successfully. To our knowledge, this is the first reported case of dystrophic calcification occurring within the uterus in a pregnant pig.
