Resumo
Mediterranean Cypress pollen is the major aerospore component in winter and early spring. Several recent studies have assessed the incidence of respiratory allergy to this pollen. A personal series of patients encountered in 1994-96 revealed a 9.33% incidence of positive prick-test responses to Cypress pollen among a population with atopical status. That series included 16 (19.05%) single and 68 (80.95%) multiple allergy sufferers. Among the former the symptoms encountered were rhinitis (62.5%) and asthma (37.5%). Given the ever-increasing incidence of Cypress pollen allergy, there is a need to restrict the planting of the tree for ornamental purposes, especially in areas with a high pollen count.
