Two different clinical forms of squamous cell carcinoma (SCC) in the perineum and vulva of two mares

BackgroundGenital malignant neoplasms in mares are relatively rare. The treatment involve surgical removal of the tumour masses, chemotherapy or both.Case presentationTwo elderly warmblood mares, aged 16 and 20 were presented in University Clinic with the lumpy lesions at the region of perineum and left labia. Surgical removals of tumour masses were performed on standing animals. Removed tissues were subjected to histopathological examination which confirmed SCC.ConclusionsClinical and ultrasound examination of reproductive organs in both mares showed no inflammatory or neoplastic changes. Both mares healed within 2weeks after surgery and showed no signs of tumour recurrence for the following year despite no chemotherapy treatment.
