Malignant fibrous histiocytoma (MFH) is the most common soft-tissue sarcoma occurring in adults. This entity was first described by O'Brian and Stout in 1964. Apart from the soft-tissues, this tumor has been reported to occur in all other parts of the body including bone. It has male predilection and is usually noticed in the fifth to seventh decades of life. It commonly affects extremities and retroperitoneum, whereas involvement of the head and neck region is comparatively rare. However, when the head and neck region is affected, the most common sites are the maxillary sinus and the nasal cavity, in which case, later involvement of the maxillary alveolar bone can happen. The oral cavity is a relatively less common site for MFH. This article describes clinical, computed tomographic and microscopic features of a MFH of the maxillary alveolar ridge extending to the hard palate in a 46-year-old female patient. Histogenesis, advanced imaging features, differential diagnosis, and management of MFH are also discussed.

Abstract in Chinese

上颌牙槽嵴延伸至硬腭的恶性纤维组织细胞瘤 摘要 恶性纤维组织细胞瘤(MFH)是发生在成人的最常见的软组织肉瘤。这种病例实体在1964就由O«SQ»Brian和Stout第一次描述了。除了发生在软组织,该肿瘤已经有报道说在身体的所有其他部分发生包括骨都能发生。它偏向于发生于男性,通常是在一生的第五到第七个十年。它通常影响四肢及后腹腔,而头部和颈部区域是比较罕见的。然而,在头部和颈部区域的影响,最常见的部位为上颌窦和鼻腔,在这种情况下,较晚可发生上颌牙槽骨受累。口腔是一个发生恶性纤维组织细胞瘤相对少见的部位。本文介绍了一个46岁的女性患者的上颌牙槽嵴延伸至硬腭的恶性纤维组织细胞瘤的临床,CT和微观特征。组织发生,晚期的显像特点,鉴别诊断以及恶性纤维组织细胞瘤的处理。 关键词:组织细胞瘤,恶性纤维瘤,上颌骨,口腔,肉瘤
