Case presentation A 26-year-old Caucasian man with a known history of a large hemangioma of his head and neck presented with sleep-disordered breathing to the sleep unit of our hospital. Severe obstructive sleep apnea syndrome was revealed on polysomnography. Nasal continuous positive airway pressure was implemented effectively reducing daytime hypersomnolence and significantly improving sleep parameters. After three years of adherent use the patient remains in a good condition and the hemangioma is stable. Conclusion Application of continuous positive airway pressure can be an effective treatment for patients with obstructive sleep apnea syndrome complicated with vascular tumors. Periodic follow-up of these patients is necessary as little is known about the long-term effects of continuous positive airway pressure therapy. Introduction Obstructive sleep apnea syndrome OSAS is the most common sleep-related breathing disorder with a worldwide prevalence of 4 and 2 in middle-aged men and women respectively 1 . The clinical manifestations in patients with this condition include daytime hypersomnolence neurocognitive dysfunction cardiovascular disease and metabolic disorders 2 . There are many risk factors for the development of OSAS including alterations in upper airway anatomy in some patients which predisposes them to upper airway obstruction by increasing pharyngeal collapsibility 3 . An uncommon cause of anatomic narrowing of the upper airway is soft tissue tumors of
