A 69-year-old Caucasian woman presented with chronic lymphocytic leukaemia (CLL; stage 1-Rai System), significant oropharyngeal lymphoid enlargement, snoring and fatigue. Overnight polysomnography revealed moderately severe obstructive sleep apnoea (OSA), which was managed successfully with oral appliance therapy with resolution of snoring and daytime fatigue. Structural abnormalities of the upper airways are known to cause OSA. Airway narrowing can result from bony structural abnormalities, nasopharyngeal growth, soft tissue redundancy, macroglossia, malignant and benign growth of the upper aero-digestive tract, and adenotonsilar enlargement. Clinicians should be encouraged to consider a diagnosis of OSA in patients with CLL when they present with symptoms of worsening fatigue.
