A rare case of parosteal osteosarcoma of the maxilla in a 14 year old and a review of the current literature

AbstractParosteal osteosarcoma of craniofacial location was first described in 1961 and since then, less than 20 cases have been reported in the English literature. This rare tumor of the jaws most commonly affects middle aged men, is considered a low grade, well ‐differentiated neoplasm, characterized by spindle cell stroma with minimal atypia and rare mitotic figures, separating irregular well‐developed trabeculae of woven bone. It is considered to have a favorable prognosis and low metastatic potential if treated by radical excision, compared to conve ntional and periosteal osteosarcomas. Clinically and radiographically it can be mistaken for a benign lesion, therefore high clinical suspicion is advised. Herein we report a case of parosteal osteosarcoma located at the posterior maxilla in a 14 year old male and review of the literature with respe ct to clinical, radiographic and histopathological features of these lesions.
