Churg–Strauss syndrome

Churg–Strauss syndrome, also known as eosinophilic granulomatosis with polyangiitis, is a rare vasculitis characterized by asthma, eosinophilia, and systemic vasculitis affecting small to medium-sized vessels. It is clinically significant due to its potential to cause severe organ damage, particularly in the lungs and kidneys, necessitating early diagnosis and treatment. A key association is its occurrence in patients with a history of asthma or allergic rhinitis, highlighting the need for vigilance in these populations.
