Nonossifying fibroma is usually seen in long bones, and very rarely encountered in the mandible.<BR>We reported a case of nonossifying fibroma in the mandible of a 7-year-old boy. He had complained of diffuse swelling in his left parotid area for a month. At his first visit to our department on March 5, 1986, the diffuse swelling, elastic hard in consistency, was observed on his left parotid area. He did not complain of spontaneous pain, but palpation of that area revealed slight tenderness. Previous parotid sialography, performed by an otorhinolaryngologist, revealed no abnormality. Roentgenography showed multilocular radiolucent lesion on his left ramus of the mandible. The radiolucency had thin osteosclerotic margin containing no abnormal radio-opacity.<BR>Histopathological specimen from surgical curettage, revealed fibroblast-like cells which formed whorled bundles and multinucleated giant cells scattered in the stroma. There was noepithelial element or bone in the lesion. Foam cell was not detected in the specimen. Histopathological diagnosis was established as nonossifying fibroma.<BR>Our review of literature about nonossifying fibroma in jaw bones indicated only eight casesincluding the present one. All cases were in the mandible, frequently at the posterior region.Five patients out of eight were female, and seven were under 30 years old. Roentgenography revealed multilocular lesion in five cases, and monolocular in three. Histopathology showed whorled pattern of fibroblasts and multinucleated giant cells in all cases. Foam cells were seen in five cases. All cases were treated with surgical procedures.
