Multiple eruptive keratoacanthoma and immunity disorders.
A 68-year-old woman presents multiple keratoacanthoma of the Witten and Zak type associated with immunity disorders. A dramatic regression of the lesions is noticed while the patient is treated with an association of loratadine and ranitidine. Hypotheses are proposed in view of a possible role of ranitidine, an anti-H2 antihistaminic.
