Oral ulceration: an unusual manifestation of Churg-Strauss syndrome.

Churg-Strauss Syndrome (CSS) is a relatively rare entity characterized by asthma, transient pulmonary infiltrates, eosinophilia and systemic vasculitis. Oral ulceration is a possible clinical manifestation of some systemic vasculitides, such as Wegener's granulomatosis (WG) or giant cell arteritis, but has never been reported with Churg-Strauss syndrome. We report the first observation of a palatine ulceration in a 15-year-old girl with Churg-Strauss syndrome.
