Clinical pictureThis section has been translated automatically.
The literature reports numerous cases of irritant and allergic reactions after contact with the cup primrose. The most common allergic contact eczema today is observed in connection with domestic or hobby gardening activities.
In a larger (Italian) collective of patients with potential contact sensitization (n=24,000), Bongiorni L et al (2015) demonstrated a primin sensitization of 1.9%, with women (2.6%) more frequently sensitized than men (0.5%). In certain areas of Italy (Pordonne) even higher sebisbilisation rates (up to 6%) were detected.
Occupational primrose allergies among gardeners or florists are rare. Cross-reactivity may occur in contact with other plants and wood species containing quinones with related structure, such as exotic wood species(Dalbergia species, rosewood) such as teak or rosewood. Related chinoid constituents are also found in other primrose species, orchid species, etc. as well as marine animals (e.g. in natural sponges).
