title: [Two patients with osteochondroma of the cervical spine].
abstract: In two patients, both women of 32 years old, who had a local tumour in the neck firmly attached to the spine, radiologic imaging and biopsy led to the diagnosis of osteochondroma. Both patients recovered, but one had an episode of atrophy of the M. trapezius and the M. rhomboideus. If a solid mass is palpated in the neck a malignant process and cervical exostosis should be considered in the differential diagnosis. Exostoses usually are benign symptomless tumours, diagnosed in the second or third decade of life. They may compress spinal nerves and in rare cases cause severe complications by compression of vital structures such as myelum and arteries. An exostosis should be resected only if it is symptomatic or if a malignant process is suspected. In case of doubt surgical intervention is indicated with special attention to surrounding structures such as nerves and blood vessels.
