The myxoma(odontogenic myxoma, myxofibroma) of the jaws is a benign, usually slow-growing infiltrative tumor of connectice tissue. This article describes a case history of the treatment of recurred odontogenic myxofibroma in the maxilla and further discusses the appropriate management of such cases with reference to the literature review. A 55-year-old male patient presented with a gingival swelling in the right side of maxilla. He had history of second time recurred disease. Microscopically, a high cellularity fibrous tumor with fibroblastic cells was observed. Tumor cells were composed of stellate and spindle shaped fibroblasts. Islands of odontogenic epithelium were seen in the specimen. The final diagnosis was made with odontogenic myxofibroma in consideration of twice-time recurrences and histological characteristics. Because of the high likelihood of recurrence, an accurate differential diagnosis of pathology at the time of initial visit is very important in determining treatment options, and immunohistochemical tests may be helpful. Also close following up is required.(155 words)
