[Inflammatory myofibroblastic pseudotumor of the tongue].
BACKGROUND
Inflammatory myofibroblastic tumor (IMT) is a new entity recently described, first in the lung. IMT are found throughout the body.


METHODS
We report a very rare tongue localization in a 22-year-old white woman. After a first diagnosis of fibrosarcoma, a new examination of the slide and immunohistochemical examination led to the definitive diagnosis of inflammatory myofibroblastic tumor of the tongue and not fibrosarcoma.


CONCLUSIONS
IMT are rarely encountered in the head and neck region. Only 2 cases of IMT of the tongue have been reported in the world literature. Diagnosis of IMT is immunohistochemical. Spindle cells were reacted for smooth-muscle actin and vimentin. Treatment is surgical. The contribution of radiotherapy is not clear because of the small population of patients studied.
