Biography

Introduction: Primary osteosarcoma (OS) is the second most common primary bone malignancy, the first being multiple myeloma. OS occurs in the second decade, with a predilection for ends of long bones.Head and neck involvement is seen in 2–9% with extragnathic craniofacial bones in 1–2% of cases.Small cell OS (SCO) constitutes 1.3–4% of all OS, skeletal distribution and age range being similar.
Materials–Methods: We report two rares osteosarcoma and we done the review of the litterature about the management and the outcome about intracranial osteosarcoma in our department of neurosurgery.
Results: it is two osteosarcoma cases about a 72-year-old man and one 49-year-old man who both mimiking first meningioma. The first cases is an unsual site parietal and the second case is occipital.the both benefited surgery with excision and exam of histology confirm diagnosis. But the first case died 15 days after surgery in intensive unit care and the second cases died after one year, he benefited surgery and chemotherapy.
Conclusion: Small cell osteosarcoma (SCO) is an extremely uncommon entity that mainly involves the metaphysis of long bones and, rarely, the skull. Histopathology is the key to establishing the correct diagnosis, including subtyping for appropriate management and prognostication, as radiological features are not specific.
