Salivary gland involvement in Wegener's granulomatosis.

When salivary gland enlargement occurs in association with other ENT symptoms, Wegener's granulomatosis should be considered in the differential diagnosis. An early anti-neutrophil cytoplasmic antibody (ANCA) test may aid diagnosis. Effective medical treatment exists and, once the diagnosis has been made, therapeutic excision of the affected gland may be unnecessary. The fourth and fifth cases in the literature of salivary gland involvement in Wegener's granulomatosis are reported.
