Skin Lesions and Environmental Exposures: Aromatic compounds with polar or ionic substituents are typically sensitizing agents e. Relative humidity, ambient temperature, and season of the year also play roles in development of allergic contact dermatitis.
Allergen factors include the physiochemical nature of the allergen e. He had the groin and belt line rash for 2 weeks and wanted to know if they were related.
Cross-reactivity with antigenically similar substances may occur.
Join our CME mailing list! During the induction phase, which may last from 4 days to several weeks usually about 14 to 21 daysthe development of complete allergic sensitization occurs as the allergen comes in contact with the skin.
On subsequent contact with the complete antigen, the effector cells release lymphokines that may result in rapid and severe, local inflammation.
Page Share Cite Suggested Citation: Persons who have histories of atopic dermatitis have been reported to have decreased risk of developing allergic dermatitis but increased risk of developing irritant dermatitis. The patient had seen a local Dermatologist trained Nurse Practitioner and was diagnosed with Tinea and treated with topical antifungal with no positive results.
The patient was treated with Mentazol mg BID for 5 days. The sensitized T cells proliferate in the paracortical regions of the lymph nodes and produce effector and memory lymphocytes that remain in the general circulation.
With the exception of nickel, cobalt, and some forms of chromium, most metals do not produce sensitization.
Once a person has been sensitized to an offending substance, further exposure may result in relatively rapid development of local inflammation with erythema, papule formation, induration, and weeping vesiculation.
The allergens are haptens rather than complete antigens; they must penetrate the skin and combine with endogenous proteins to form full antigens. Potentially, the entire skin surface could become involved a condition known as erythroderma or exfoliative dermatitis. In addition, chemicals that are structurally similar to the original sensitizing agent may provoke recall of the specifically sensitized lymphocytes, a phenomenon known as cross-sensitization.
Persons sensitized to Rhus plants such as poison ivy or poison oak may be sensitive to cross-reacting substances found in exotic trees and their derivative products lacquers, varnishes, and oils.Case Study It’s Monday morning and the first student to be seen today is Maria.
