Plain-English summary
A 1-year-old spayed female German shepherd was brought to the vet for a diaphragmatic hernia repair. During surgery, the vet found a large tumor on the diaphragm, which was diagnosed as a peripheral nerve sheath tumor (PNST) with bone-like tissue. Although the dog was sent home after four days, she started having trouble breathing a week later, and her owners chose to euthanize her. Unfortunately, she did not recover after the surgery, and a necropsy was not performed to learn more about her condition.

Abstract
A 12-month-old, spayed female German shepherd dog was referred to the Veterinary Teaching Hospital for repair of a diaphragmatic hernia. Abdominal exploration revealed an intact diaphragm, but thoracic exploration revealed a large mass originating from the diaphragm. Resection of the mass was incomplete and required reconstruction of the diaphragm. On histopathology, the mass was composed mainly of spindle-shaped cells with occasional areas of osseous and chondroid tissue. The tumor was diagnosed as a peripheral nerve sheath tumor (PNST) with chondro-osseous differentiation. The dog was released four days after surgery; however, she began having difficulty breathing seven days after discharge, and the owners elected euthanasia. A necropsy was not performed. This is the first known report of a PNST originating in the diaphragm of a dog.
