Plain-English summary
A 6-month-old female Yorkshire Terrier was brought to the vet because she was limping on her left front leg. X-rays showed a bone lesion in her upper arm that was causing a fracture. The vet decided to amputate the leg, and after the surgery, the puppy recovered well. The diagnosis was an aneurysmal bone cyst, which is unusual in such a young dog, as these are typically found in older, larger breeds.

Abstract
A 6-month-old female Yorkshire Terrier was examined because of acute left forelimb lameness secondary to a Salter-Harris type IV fracture of the lateral condyle of the humerus. Radiography revealed an eccentric, osteolytic lesion in the distal humeral metaphysis associated with a pathologic fracture. The limb was amputated, and the dog recovered. Microscopic examination revealed an extensive zone of hemorrhage and dilated coalescent spaces, which were filled with blood. Hemosiderin-laden macrophages and multinucleated giant cells were observed throughout the stroma. On the basis of clinical, radiographic, and histologic examinations, a diagnosis of aneurysmal bone cyst was made. Aneurysmal bone cysts generally have been detected in 11- to 13-year-old, medium- to large-sized dogs. They can develop secondary to malignant processes.
