Allergic granulomatosis and angiitis in the absence of asthma and blood eosinophilia: a rare presentation of limited Churg-Strauss syndrome
- 104 Downloads
Allergic granulomatosis and angiitis, also known as Churg-Strauss syndrome (CSS), is an uncommon vasculitis of unknown etiology. We report a 21-year-old male patient with fatigue, dry cough, and progressive dyspnea. He had no history of asthma or eosinophilia. Thorax computed tomography showed bullous/cystic areas with thin walls in varying sizes (5–15 mm). Histopathological examination of the open lung biopsy revealed granulomatous infiltration with histiocytes and eosinophilic leukocytes. This extremely rare variant of CSS is discussed.
