Calcified uterine leiomyoma: A rare association with inguinal hernia in a dog

A 10-year-old intact female Pug dog was presented with a 3-month history of left inguinal distension. A tentative diagnosis of cystic endometrial hyperplasia and uterine mineralisation with inguinal herniation was made together with palpation, abdominal radiographic and ultrasonographic examination. Ovariohysterectomy and hernioplasty were simultaneously performed. The left uterine horn was herniated through the inguinal ring. On histopathology, multinodular calcified uterine leiomyoma associated with a diffuse endometrial cystic hyperplasia was diagnosed. Uterine herniation should be considered in the differential diagnosis of inguinal mass in an intact bitch, and uterine neoplasia may be found as an underlying disease.
