Surgical resection of a dysgerminoma in a mare.

The study reports the successful surgical removal of a rare ovarian tumor, a dysgerminoma, found in a mare, which showed no health complications post-surgery and was in foal after seven months.

Overview

In the study, a mare was referred for further evaluation after a mass was detected in the left section of her abdomen during a routine postpartum reproductive check-up. The mare was in a healthy condition and had no previous medical issues. An ultrasonographic examination of the mass confirmed its existence, but its source was unclear. All routine hematological and serum biochemistry tests were with normal limits.

Procedure and Treatment

• The initial approach was a conservative treatment using antibiotics, however, the mass kept growing.
• Seeing no regression in the mass, the decision was made to opt for surgery. The mass was surgically removed and was found to be lodged in the left ovary of the mare.

Post-surgery Results

• Following the surgery, the mare temporarily experienced some abdominal pain, but no other complications arose.
• Seven months post-surgery, the mare was pregnant, indicating good health and recovery.

Diagnosis

• The removed mass was subjected to histological tests, which revealed the mass to be a dysgerminoma. Dysgerminomas are rare ovarian tumors originating from the germ cell.
