摘要
The study objective is to present a rare clinical case of an aggressive myofibroblastic tumor of the tongue.Clinical case. A 24-year-old patient was revealed a 44 × 25 × 50 mm volumetric formation of the left side of the tongue spreading to the contralateral side and bottom of the oral cavity. The patient denied injuries or chronic autoimmune diseases. Additional studies did not reveal failure of other organs or systems. Histological conclusion: malignant spindle-polymorphic cell neoplasm with myxomatosis, perineal growth, muscle fiber infiltration and their death. An immunohistochemistry revealed expression of vimentin, CD34, S100; Ki-67 – 30 % in tumor cells. He was diagnosed with T3N0M0 fibrosarcoma of the tongue. Subtotal resection of the tongue with simultaneous microsurgical plasty via re-activated radiation autograft was performed. According to morphological study of the removed tissues, he was finally diagnosed with an aggressive inflammatory myofibroblastic tumor of the tongue. Observation period at the time of writing was 15 months. The patient eats solid food, sound pronunciation is restored in full. There are no signs of relapse or metastasis.Conclusion. Diagnostics of an inflammatory myofibroblastic tumor of the oral cavity is complex and depends on clinical and morphological features of a particular tumor. We need reliable criteria to differentiate aggressive forms of inflammatory myofibroblastic tumor of the tongue from non-aggressive ones to choose treatment. The main difficulties arise in determining the resection volume and predicting relapse or metastasis.
