Plain-English summary
A 10-year-old neutered male cross-bred cat was brought to the vet because of a solid mass on the right side of his chest, which was attached to the ribs. After imaging tests, the mass was found to be a type of tumor called multilobular osteochondrosarcoma, originating from the cartilage of the ribs. The vet performed a major surgery to remove the tumor, taking out several pieces of cartilage and reconstructing the chest wall with artificial materials. The cat recovered well and remained healthy for about four years after the surgery.

Abstract
A 10-year-old neutered male cross-bred cat was referred to our clinic for a solid mass tightly fixed to the right side of the thoracic wall from the 2nd to 4th ribs. Computed tomography revealed the mass had remarkable calcifications and arose from the 3rd costal cartilage. After removal, it was diagnosed histopathologically as a multilobular osteochondrosarcoma (MLO). For tumor resection, extremely wide surgical margins included 6 costal cartilages and 3 sternal segments were required; however, the tumor was successfully resected, followed by reconstruction of the thoracic wall using artificial materials. The cat recovered uneventfully and was good in health for ~4 y. This is apparently the first report of surgical resection of MLO from the costal cartilage of a cat. Key clinical message: To our knowledge, this is the first report of MLO from the costal cartilage in a cat, demonstrating aggressive surgical resection despite extremely wide surgical margins.
