Abstract

Lipoma is considered a benign tumor of adipose tissue that typically develops in subcutaneous tissue. While this type of tumor is common in older and obese dogs, intermuscular lipomas are rare in veterinary medicine. This report represents the clinical signs, physical examination, and diagnostic imaging findings of intermuscular lipoma in the axillary region of a 12-year-old intact male mixed terrier dog.Diagnostic tests, including ultrasonography, Computed Tomography (CT), and Fine-needle aspiration, were performed. The mass was removed entirely with blunt dissection with a safe margin under general anesthesia. A large fatty tumor between the deep pectoralis and superficial pectoralis muscles was found during surgery. In macroscopic and microscopic examinations, a non-encapsulated mass, with a soft, greasy consistency, containing differentiated and benign adipocytes was observed, indicating lipoma. In the examination 6 months after surgery, the patient showed no lameness and other neurological complications, and there was no sign of recurrence of the mass. Intermuscular lipoma is rarer than other types of lipomas. Complete surgical excision is the optimal treatment for intermuscular lipomas, yielding an excellent prognosis post-surgery
