Paediatric Wegener's granulomatosis: two case histories and a review of the literature.

Wegener's granulomatosis is a rare disease in children, with only 37 previous cases described in the literature. We report two new cases, one in an 11-year-old child who presented with cavitating nodules in the right upper lung field as well as a maxillary sinusitis and nasal perforation, and the other in a 16-year-old female who initially presented with a purulent maxillary sinusitis and only later developed an orbital pseudotumour.
