Abstract

Myofibroma is a rare benign proliferation of fibroblastic tissue occurring exclusively in infants and children. Myofibroma rarely arises in the oral and maxillofacial region. We report a case of a myofibroma-like tumor arising in the tongue of a 50-year-old man. He had noticed gradual swelling of the right side of the tongue. Two weeks later he was referred to our hospital for treatment. A soft elastic mass arising in the right margin of the tongue, measuring 10 ×10 ×12 mm, was recognized. Surgical resection of the tumor was performed with the patient under local anesthesia. Immunohistochemical staining was very useful for establishing the diagnosis of a myofibroma-like tumor. This tumor was positive for vimentin and HHF-35 and negative for desimin. The patient has shown no signs of recurrence during 1 year of follow-up.
