口底部に発生した成人型横紋筋腫の1例 A case of adult rhabdomyoma in the floor of the mouth
Adult rhabdomyoma is rare benign tumor of muscle origin usually occurring in the head and neck region. Only a few cases of this disease have been reported in the literature.<BR>We describe a 63-year-old man with an adult rhabdomyoma arising in the floor of the mouth. The patient was found to have a mass occurring in the right side of the floor of the mouth on examination at a dental clinic. When he visited our department on June 16, 1999, a mass measuring 25×35mm was found in the right side of the floor of the mouth. We felt pseudofluctuations on the normal mucosa. CT imaging demonstrated a low-density mass. The Clinical diagnosis was a bengin tumor of the right side of the floor of the mouth. The tumor was surgically removed on July 7, 1999. It was an elastic, reddish brown, encapsulated tumor measuring 50×40×18mm. Histological examination revealed an adult rhabdomyoma.
