Endometritis and cystic endometrial hyperplasia in a goat.

Histologic examination was performed on uterine biopsy samples of irregular cystic masses noted during caesarean section of a 2-year-old female Boer goat. Histopathologic examination revealed multifocal erosions of the superficial epithelium and multifocal infiltration of the endometrium by widely scattered viable and degenerate neutrophils, lymphocytes, and plasma cells admixed with mild amounts of cellular debris and hemorrhage. The endometrium was markedly expanded by many irregular cystic and hyperplastic glands. This is the first case report of endometritis and cystic endometrial hyperplasia in a goat in North America.
