Original publication title: Fetal rhabdomyoma in a Thoroughbred filly.

Plain-English summary

A newborn Thoroughbred filly was found to have a large mass on her jaw shortly after birth. The mass was surgically removed while she was under anesthesia, and tests confirmed it was a type of tumor called a fetal rhabdomyoma. Six months later, the filly was examined again and showed no signs of any problems. She recovered well after the surgery and is doing fine now.

Abstract

A newborn Thoroughbred filly presented with a large mass located on the ventro-rostral aspect of the mandible. The mass was surgically removed under general anaesthesia. Upon gross examination, the mass was well circumscribed with a heterogeneous lobulated appearance. The results of histopathology and immunohistochemistry were consistent with a diagnosis of congenital fetal rhabdomyoma. On follow-up at six months post-surgical excision, no abnormalities were noted on clinical examination.
