Plain-English summary
A 25-year-old mixed-breed horse was taken to a veterinary hospital because it had several lumps on its right front leg and belly. Tests on one of the lumps and a nearby lymph node suggested that it had a type of cancer called myxosarcoma, which is a malignant tumor. Unfortunately, because the prognosis was not good, the decision was made to euthanize the horse. After examining the horse's tissues, the diagnosis of metastatic cutaneous myxosarcoma was confirmed. This type of tumor is rare, but veterinarians should keep it in mind when looking at skin tumors in horses.
Abstract
A 25-year-old mixed-breed equine with separate nodular cutaneous lesions in the right thoracic limb (RTL) and right ventral abdominal region was admitted to a Veterinary Hospital in Belo Horizonte, Minas Gerais. Fine-needle aspiration cytology was performed on the RTL lesion and superficial cervical lymph node, and the results were suggestive of a malignant neoplasm known as myxosarcoma. Due to the unfavorable prognosis, the animal was euthanized. Based on the macroscopic and microscopic findings, the diagnosis of metastatic cutaneous myxosarcoma was confirmed. Although rare, this tumor should be considered as a differential diagnosis for cutaneous neoplasms in this species.
