Plain-English summary
A 9-year-old neutered male Shih Tzu was brought to the vet because of three hard lumps under the skin between his shoulder blades. After examining the lumps, the vet found they were made of mature bone tissue, and there were no signs of any other health issues or injuries. The dog was diagnosed with a rare condition called primary osteoma cutis, which is unusual in dogs. Fortunately, there were no complications, and the dog did not require any treatment since the condition was benign.

Abstract
A 9-year-old neutered male Shih Tzu was presented with three contiguous firm nodules in the subcutaneous tissue of the interscapular region. Histopathological examination revealed that the nodules consisted of mature lamellar bone with a Haversian system, with no apparent lesion around the bone. Clinical examination revealed that the dog had no underlying disease and no history of trauma at the lesion site. Based on these findings and on the medical history, a diagnosis of primary osteoma cutis was made. Osteoma cutis is rare in both human and veterinary medicine, and most dogs reported to have secondary osteoma cutis. To our knowledge, this case is only the second report of primary osteoma cutis in a dog.
