Which of the following is a common manifestation of atopy?

Atopy is a tendency to mount IgE-mediated responses to common environmental antigens, leading to mucosal allergic diseases. A classic manifestation is allergic rhinitis, with symptoms like sneezing, itchy eyes and nose, nasal itching, rhinorrhea, and congestion, often seasonal or perennial and frequently coexisting with asthma or atopic dermatitis. This makes allergic rhinitis the most typical and common expression of atopy. Viral upper respiratory infections are infectious, not driven by IgE-mediated allergy. The other findings—Charcot-Leyden crystals and Curschmann's spirals—reflect eosinophilic inflammation seen in asthma and other allergic diseases, but they are not primary manifestations of atopy themselves; they are laboratory or pathologic features of asthma rather than true systemic manifestations like allergic rhinitis.
