This report describes the results of clinical, cytological and histopathological findings associated with subcutaneous extraskeletal osteosarcoma of a 05 years old Australian Silky Terrier. The tumor was located on the head above the frontal and parietal part of the skull. A definitive diagnosis was based on histological examination of the mass. Even though chemotherapy was suggested owner declined it therefore wide surgical resection of the tumor was performed with appropriate supportive therapy. However, the dog died few months after the initial presentation. To our knowledge, this case report is the first description of extraskeletal osteosarcoma of the head in a dog in Sri Lanka with the history of swelling on the head, lethargy, head pressing against objects and anorexia. Extraskeletal osteosarcoma should be considered in the differential diagnosis of soft tissue swelling in head in dogs. It is highly recommended to use advance diagnostic aids in order to rule out primary bone tumors.
