ABSTRACT
The spine is a rare localization of osteoid osteoma and the coccyx even more exceptional. We report a case of osteoid osteoma of the coccyx in a young man who consulted for sacrococcygeal pain partially relieved with salicylates. Computed tomography of the region demonstrated a typical osteoid osteoma lesion. CT-guided localization enabled complete resection of the nidus as demonstrated by the CT of the operative specimen Pathology confirmed the diagnosis of osteoid osteoma. Outcome has been quite favorable at two years.

A paraganglioma is a rare tumor composed of chromaffin cells. Malignant paraganglioma is a very rare presentation diagnosed by local recurrence after total resection of the primary mass or findings of distant metastasis. We report a case of a 30-year-old man who had undergone a carotid body tumor resection 10 years before and who presented to us with recurrence of the tumor associated with lymph node, vertebra and skull metastasis. The diagnosis of malignant paraganglioma was based on loco-regional and distant metastasis.
