Contact and microbial allergy in pompholyx.

Contact sensitivity to medicaments and other chemical allergens has been observed in about 30% of 364 patients with pompholyx. Pompholyx is a recurrent vesicular eruption which increases the incidence of contact sensitivity. The majority of patients tested by means of intradermal and cultural tests did not show any relevant finding on the microbial nature, allergic or not, of pompholyx.
