A cross-sectional study was done to determine the frequency of cutaneous sensibility to aeroallergens and variations related to residence area. In a period of time from June 1994 to June 1995, we analyzed 101 patients residents in the Comarca Lagunera diagnosed as having allergic bronchial asthma. The patients were highly sensitive to pollen grains: Cynodon Dactylon (70%), Chenopodium (69%), Rusian Thistle (63%), Rye Grass (61%), Zea Maiz and Prosopis (57%). The sensitivity to molds was less: Candida (22%), Helmintosporium (18%) and Cephalosporium (16%). House Dust was positive in 55% and Dermatophagoides in 35%. Cotton hypersensitivity was poor (7%). There were not differences in cutaneous reactivity related with residence area.
