Les pollinoses de proximité ne sont-elles que des cas cliniques ? Revue de la littérature à propos de cinq observations

Pollinosis of proximity is due to plant species that emit their pollen in a limited perimeter and affect patients who stay in this limited perimeter. The aim of this present work, in addition to reporting five well-documented cases (two cases due to dandelion, one to lupin, one to cyclamen, and one to mimosa pollen), was to review this type of allergy, which is not rare among individuals who are highly exposed to these plants, notably florists and gardeners, concerning which epidemiologic studies have been carried out. Because of the large variety of species that can be involved, these pollinoses can likewise affect the general population, especially atopics, if the conditions of exposure are favourable. Finally, the incidence of these allergies is not well known, while they are regularly the subjects of case reports. Because of the lack of standardized allergen extracts, diagnosis of these allergies depends on the clinical history.
