Histologically, osteochondromas are hamartomas developed from endochondral ossification which are coated with a thin cartilage layer [1]. Epidemiologically, these are the most frequent benign tumor, after nonossifying fibromas and metaphyseal lacunae, representing, in the Unni series [2], about 40 % of all benign tumors, and they are located preferentially at the metaphyseal level of long bones...

The laryngeal mask airway (LMA) is an airway management device that is used to establish and maintain a patent airway for the patient. A palatal torus is a common benign bony exostosis, usually located in the midline of the palate, beneath the palatal mucosa. It should be recognized by the CRNA during the preoperative anesthetic assessment. A palatal torus can hinder insertion of the LMA when u...

Florid reactive periostitis is a pronounced periosteal reaction, usually affecting the hands and feet, for which there is no obvious cause. It is rare in children and in long bones. We report an unusual case of florid reactive periostitis in a ten-year-old girl that involved both bones of the forearm. The lesion resolved over a period of one year, leaving a residual exostosis. She developed a p...

Stenosing tenosynovitis of the extensor digitorum longus tendon is an injury related to ultramarathon running. A 32-year-old male ultramarathon runner developed chronic tenosynovitis of the ankle dorsiflexors. He was diagnosed with extensor digitorum longus tenosynovitis caused by talar head impingement associated with exostosis. He failed to respond to non-operative management and decided to u...

Osteochondroma of the spine is rare. It may present in solitary or multiple form (hereditary multiple exostoses). Herein, we report a case of an 18-year-old male who was diagnosed with thoracic osteochondroma, originating from the D4 vertebra with intraspinal extension and spinal cord compression in hereditary multiple exostosis. The patient was managed with surgery. Complete tumour excision wa...
