Obstructive sleep apnea with pulmonary hypertension and cor-pulmonale in an 11-year-old Nigerian boy with sino-nasal non-hodgkin lymphoma

Children are predominantly nasal breathers, therefore obstruction of the nasal passage presents early with difficulty in breathing; however, with advance in age they soon adapt to mouth breathing. Chronic upper airway obstruction may result in cardiovascular complications such as pulmonary hypertension, right ventricular heart failure, and also renal disease. Therefore, we report the case of an 11-year-old Nigerian boy who had upper airway obstruction complicated with sleep apnea, pulmonary hypertension and cor-pulmonale resulting from sino-nasal (nasopharyngeal) non-Hodgkin lymphoma which is rare in African children
