title: [Bone metastasis revealing a primary prostate cancer].
abstract: Spiculated reactive periosteal bone is usually found in cases of primary malignant bone tumors; rarely in secondary bone lesions. The authors report a case of bone tumor of the clavicle in a 62 year-old patient with "sunburst " periosteal reaction on radiographs. The metastatic nature of this lesion from an unknown prostate carcinoma was confirmed by immunohistochemical studies of the clavicle biopsy. Tumorectomy was performed and the patient's status is stable with a follow-up of 10 months.
