Uterine serosal inclusion cysts in a bitch

Abstract

A six-year-old, pluriparous German shepherd dog bitch was presented with an abnormal vaginal discharge of several weeks' duration. Clinical signs and radiographic and ultrasonographic findings supported an initial diagnosis of segmental cystic endometrial hyperplasia, and ovariohysterectomy was performed. Macroscopically, the uterus appeared normal except for one large and several smaller cysts attached to its antimesometrial side. These cysts were restricted to a small area of the left uterine horn. The histological diagnosis was serosal inclusion cysts. The clinical findings, gross pathology and histopathology are described and discussed.
