title: Tumors of the oral cavity and pharynx.
abstract: We have compiled all the reported cases of smooth muscle (stromal) tumors of the oral cavity and pharynx from 1884 through 1996. Our collective data included 139 leiomyomas (LM) and 68 leiomyosarcomas (LMS); but because we did not have sufficient information for 13 cases of LM, we report on only 126; and we report on only 66 of 68 cases of LMS. The peak age of incidence was 40 to 49 years for benign tumors and 50 to 59 years for malignant lesions, with the incidence in men slightly predominating over that in women. The most common sites of LM of the oral cavity and pharynx were the lips, tongue, and hard and soft palate. The most common sites of LMS included the maxilla and mandible. More than 40% of LMs presented as an intraoral mass, and more than half were known to be present for longer than 1 year. About 10% presented with pain, difficulty chewing or swallowing, swelling, toothache or loose teeth, or a combination of these symptoms. Patients with LMS were much more likely to have obvious symptoms of shorter duration, and one-third presented with pain or swelling (or both). Other relatively common symptoms of LMS included tenderness, interference with dentures, or an intraoral mass. In this review, there were almost twice as many LMs as LMSs, which was consistent with smooth muscle tumors found in other areas of the gastrointestinal tract.
