Patients with asthma, nasal polyps, and aspirin intolerance may have severe asthma with rhinosinusitis and nasal polyposis, accompanied by hives, flushing, or abdominal pain following the administration of aspirin or nonsteroidal antiinflammatory drugs (NSAIDs). Severe episodes are life-threatening (summary by Arm and Austen, 2002). [from
