Hydatidiform moles in Holstein cattle

Area of Science:

• Veterinary Pathology
• Reproductive Biology in Livestock

Background:

• Hydatidiform mole is a rare gestational trophoblastic disease.
• It involves abnormal placental development, leading to characteristic molar tissue formation.
• Occurrence in cattle, particularly Holstein breed, is infrequently reported.

Purpose of the Study:

• To report and describe two distinct cases of hydatidiform mole in Holstein cattle.
• To document the clinical context and outcomes associated with these rare events.

Main Methods:

• Case observation and description.
• Review of clinical history and reproductive events.

Main Results:

• Two Holstein cows presented with hydatidiform moles.
• The first case was identified post-term following the delivery of a healthy calf.
• The second case was diagnosed subsequent to the abortion of a fetus exhibiting osteopetrosis.

Conclusions:

• Hydatidiform moles can occur in Holstein cattle, presenting in different reproductive scenarios.
• These findings contribute to the limited literature on bovine hydatidiform moles and their associations.
