[Genital artefact ulcers appearing simultaneously in a couple].

Genital ulcers may be due to a number of causes, with the most frequent ones being of infectious, tumorous and physical etiology. The coexistence of genital lesions in a couple makes it necessary to rule out sexual transmission as a first option, as it is not always the cause. We present the case of a 78 and 73-year-old couple, both of whom presented with genital ulcers which had been developing for months and which began to manifest simultaneously. The negative results in the tests performed, the exclusion of other likely causes and the favorable evolution of the lesions suggest self-inflicted ulcers as a probable diagnosis, an infrequent form of presentation of "folie à deux". Despite its infrequent occurrence, dermatitis artefacta is a cause that should always be included in the differential diagnosis of any skin lesion, as it often goes unnoticed because of its many clinical presentations.
