A giant parapharyngeal lipoma causing obstructive sleep apnea.

Lipoma is the most common soft tissue mesenchymal neoplasm. Its occurrence is low in the oral cavity (1 to 4%) and in head and neck region (20 to 25 %). Usually asymptomatic and slowly growing, lipoma can compress neighboring cervico-facial structures causing dysphagia, dyspnea, or obstructive sleep apnea. We describe an unusual case of giant cervico-parapharyngeal lipoma causing an obstructive sleep apnea in a 69-year-old man and with the complete remove of OSA after surgical procedure.
