IntroductionDermatological manifestations of actinomycosis are classical, most often related to Actinomyces israelii. In most of the cases, they occur near to the primary focus, and in the cervicofacial area. Systemic dissemination with cutaneous distant metastasis is rare, most often related to A. israelii, too. We report an original case of upper limb actinomycosis associated with an oral localisation and due to an unusual bacteria.Case ReportA 49-year-old man was referred to the Department of dermatology for a skin lesion of the left hand and wrist. Biopsies revealed actinomycosis related to A. meyeri. Dental primary focus was identified and treated. Although the patient was lost sight of, dental eradication and prolonged antibiotics therapy allowed cutaneous improvement.DiscussionWe report an atypical case of cutaneous actinomycosis due to an Actinomyces meyeri dental infection occurring in an immunocompetent, smoking adult, with poor oral hygiene. The literature review revealed only 4 well-documented cases of cutaneous A. meyeri infections distant to dental primary focus. All of patients were males, immunocompetent, with a history of poor oral hygiene. The prognosis is favourable with adequate treatment (antibiotic therapy and surgical treatment to eradicate dental infectious entry points).Copyright © 2020 Société Nationale Française de Médecine Interne (SNFMI).
