Nasal crusting, rhinitis, and sinusitis are presentations of common conditions; however, these can also be the presenting symptoms of an underlying systemic disorder such as an infection, malignancy, or granulomatous disease. Granulomatous diseases with head and neck manifestations include Wegener's granulomatosis, Churg-Strauss syndrome, and sarcoidosis. These diseases are managed through a multidisciplinary approach that often includes otolaryngologists.
