Limited form of Churg-Strauss syndrome presenting as a mass in the neck.

A 53-year-old man was referred to the ENT department with a large mass in the left supraclavicular fossa. The histological diagnosis showed the mass to have arisen due to a granulomatous vasculitis consistent with Churg-Strauss syndrome (CSS). CSS usually comprises asthma, eosinophilia and systemic vasculitis although limited forms of the disease exist where one of these diagnostic criteria is missing. This is one such case as the patient was non-asthmatic.
