[Occupational skin allergy to alerc (Fitzroya cupressoides)].

Area of Science:

• Dermatology
• Phytochemistry
• Botany

Context:

• Fitzroya cupressoides (Alerce), a tropical tree, is increasingly recognized for its potential allergenic properties.
• Skin allergies pose a significant public health concern, necessitating identification of novel allergens.
• Understanding the phytochemical composition of plants is crucial for identifying causative agents of allergic reactions.

Purpose:

• To report a case of allergic contact dermatitis attributed to Fitzroya cupressoides (Alerce).
• To provide a comprehensive phytochemical classification of Fitzroya cupressoides.
• To detail the diagnostic methodology employed for identifying the skin allergy.

Summary:

• A case of allergic contact dermatitis is presented, confirmed to be caused by exposure to Fitzroya cupressoides.
• The study includes a detailed phytochemical analysis, identifying key compounds within the Alerce tree.
• The diagnostic approach involved patch testing and clinical evaluation, elucidating the mechanism of the allergic reaction.

Impact:

• This research contributes to the understanding of plant-induced allergies, specifically identifying Fitzroya cupressoides as a potential allergen.
• The phytochemical data enhances knowledge of Alerce's chemical constituents, with implications for ethnobotany and natural product research.
• The detailed methodology provides a valuable reference for diagnosing similar plant-based allergic contact dermatitis cases.
