Tongue tumors of pediatric patients are the most common soft tissue tumor of pediatric oral and maxillofacial tumors. There are many kind of pediatric tongue lesions such as hemangioma, lymphangioma, papilloma, and cyst. Most of these lesions are benign, but malignant tumors of tongue may be occurred. Therefore, malignancy should be ruled out. Sometimes, tongue lesions are present with dyspnea, dysphagia, dysarthria, bleeding, or cosmetic problem. We experienced a case of chronic inflammatory mass on posterior 1/3 of the tongue in 4 month old female patient. Swallowing difficulty and respiratory distress symptom occurred because of tongue mass effect. The tongue mass was confirmed as granulation tissue by microscopic examination. After excision of tongue mass, she had no problem with swallowing and breathing.
