Abstract

We report a case of inflammatory myofibroblastic tumor (IMT) of the mandible in a 13-year-old girl and discuss the cases of the literature. The patient noticed an enlarging left mandiblar mass in October of 1997, and visited our department. On examination, there was an elastic hard tumor in the left side of the mandibular molar region, measuring 30 × 24mm.<br/>  Histopathologically, the surgical removed tumor was composed of an interlacing fascicular growth pattern of spindle cells in a background of abundant collagenous stroma accompanied by an infiltration of chronic reactive inflammatory cells. Immunohistochemical analysis revealed that the tumor was reactive for vimentin and α-smooth muscle actin and negative for desmin, S100 protein, CD68 (KP-1, PGM-1), CD34, bcl-2, estrogen receptor, progesterone receptor, ALK-1, β-catenin, CD99, and pan-cytokeratin (AE1/AE3). She is well with no evidence of recurrent disease for 10 years after surgery.
