Adolescence is a period of transition to adulthood. Lipomas are very common benign slow-growing soft tissue neoplasms composed of mature adipose tissue mostly diagnosed in the fifth decade of life. The aim of the present study was to determine the prevalence of oral mucosal non-malignant lesions in the Sicilian population. To evaluate the type and frequency of self-mutilation lesions of the mouth and lips in a large group of institutionalized mentally retarded subjects.Two hundred and forty-five institutionalized mentally retarded patients were evaluated clinically by a systematic inspection of the perioral cutis, lips, tongue, oral mucosa, palate, gingivae and teeth. A 55-year-old man presented with desquamating lesions on his bilateral buccal mucosa intermittently for approximately 3 years. Morsicatio buccarum et labiorum is a form of chronic oral mucosa disease caused by habitual cheek or lip biting. Leukoedema, a grayish-white lesion of the oral mucosa in humans, was once thought to be a probable precursor to leukoplakia. In some individuals habitual cheek and lip biting becomes a fixed neurosis. Intraoral examination was performed in 300 consecutive patients, who attended the Department of Oral and Maxillofacial Surgery of the Free University Hospital, Amsterdam. "White lesions" of the oral mucosa often present problems of differential diagnosis, which are of primary importance when assessing precancerous changes in the mouth. Oral changes related to the occupation of glassblowing have been examined in 74 Danish glassblowers, consisting of 44 active glassblowers (Group 1) and 30 past glassblowers (Group 2).
