Plain-English summary

A 2.5-year-old Labrador retriever was brought in for limping in the front leg. Tests on a mass found in the upper arm suggested it was a type of tumor. Unfortunately, the dog was euthanized, and further examination confirmed it had periosteal osteosarcoma, a bone cancer affecting the long head of the triceps muscle. This case highlights the importance of early detection and diagnosis of unusual masses in pets.

Abstract

A 2.5-year-old Labrador retriever was evaluated for forelimb lameness. Fine-needle aspirates of a mass in the proximal brachium were suggestive of a mesenchymal tumor. The dog was euthanized and necropsied. Radiographic evaluation and gross and histopathological findings provided a diagnosis of periosteal osteosarcoma in the long head of the triceps.
