HU Mingjing; WANG Zhiyong

Objective @#To improve the dentist's understanding of desmoplastic fibroma of the jaw, we investigated the clinical manifestations, pathological features, treatment and prognosis of this disease.@*Methods@#The clinical data of 8 patients with desmoplastic fibroma of the jaw who were admitted to Nanjing Stomatological Hospital from 2011 to 2021 were retrospectively reviewed.@* Results @#The male-female ratio in this group was 31, the age of first onset was 32.13±15.00, and the lesions were mainly in the mandible. Histologically, the lesions was composed of mildly atypical fibroblasts and a large number of collagen fibers. The positive rates of Vimentin, α-SMA and β-catenin in the cytoplasm were 100%, 62.5% and 62.5%, respectively. The Ki-67 level in the initial patients was lower than 5%, and the S-100 protein level was 100% negative. The imaging manifestations were single-room or multichamber light-transmitting lesions with clear or irregular boundaries, with or without peripheral sclerosis. Five patients were treated with curettage for the first time; among them, two patients relapsed with poor prognosis. Three patients underwent extended resection, and all had no recurrence.@*Conclusions @# The clinical and imaging features of desmoplastic fibroma of the jaw are not specific. We mainly rely on histopathology to diagnose the disease. It has a high recurrence rate after surgery. At present, the best treatment is to extend surgical resection. Local curettage is easy to relapse and has a poor prognosis.
