Hydrometra/pseudopregnancy

Dairy goats / does are particularly prone to hydrometra (aka pseudopregnancy). It is occasionally seen in feral or meat goats.

There is a persistence of the corpus luteum and fluid accumulation in the uterus. Volumes are from 100 mls to 8 litres! In the Dutch study (Van den Brom et al 2019) farm incidence was 1 to 54%.

Neoplasms and masses

Epithelial

Adenocarcinoma of the tubular genitalia is reported in 13 of 42 goats with neoplasia of the tubular genitalia. 2737 does were the population from which these were recorded. Adenocarcinoma is more likely to have metastasis than other neoplasms.

Mesenchymal

Lohr (2013) reported on 102 tumors in 100 goats. Nonneoplastic entities included 2 cases of mammary fibroadenomatous hyperplasia and single cases of vascular hamartoma, cervical adenomatous hyperplasia, and cervical leiomyofibromatosis.

Linton et al (2020) reported finding 13 leiomyoma and 11 leiomyosarcoma in 42 does with neoplasia of the tubular genitalia.

Mixed tumors

Dockweiler et al (2017) reported on a goat with a large uterine mass. It had a collision of smooth muscle tumor and an adenocarcinoma. Metastases were of the adenocarcinoma were in the lung

Cossic et al (2018) reported a single case of uterine carcinosarcoma in a goat. The neoplasm was in the uterus only.
