Histologic characterization of primary ciliary dyskinesia chronic rhinosinusitis

Abstract

Key points We present the largest cohort of structured histopathology reports on primary ciliary dyskinesia‐related chronic rhinosinusitis (PCD‐CRS). Despite endoscopic differences, PCD‐CRS and cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) had similar structured histopathology reports. Compared to healthy patients and those with idiopathic chronic rhinosinusitis without nasal polyps, patients with PCD‐CRS had an increased neutrophil count.
