Fragrances are found in abundance in everyday life-from obvious sources such as perfumes, colognes, and air fresheners, to not-so-common sources, such as workplace exposures. Problematically, even products labeled as "fragrance free" may contain covert fragrances. Patients and physicians alike should be aware that fragrances are a common cause of allergic contact dermatitis (ACD) and that patient education is critical to treatment success. In this review, we discuss the chemistry and epidemiology of fragrance ACD, patch test considerations, skillful patient education on avoidance, and potential pitfalls for patients with fragrance allergy-all to empower treating clinicians with the knowledge to effectively address patient needs.

Inhaled and intranasal corticosteroids are widely used in the management of allergic respiratory diseases. Delayed drug hypersensitivity reactions to budesonide are a rare adverse drug reaction characterized by non-immunoglobulin E (IgE)-mediated clinical manifestations, including localized or systemic contact dermatitis, mucosal edema, and paradoxical worsening of pre-existing symptoms. However, such reactions are often underdiagnosed due to atypical presentations.

Animal allergens, particularly those from cats, dogs, and horses, are significant risk factors for the development of allergic diseases in childhood. Managing animal allergies requires allergen avoidance and, when this is not feasible, specific immunotherapy. Patient history remains the cornerstone of diagnosis, providing the foundation for diagnostic algorithms.

Rubber accelerators are chemicals used as vulcanizers in the production of rubber items and may cause contact allergy (CA). The aim of this study was to assess the worldwide prevalence of CA to rubber accelerators from the European baseline series among dermatitis patients. A comprehensive literature search across PubMed, Embase, and Web of Science yielded 106 studies with 826 543 individuals patch tested between 1984 and 2023.
