title: Actinomyces meyeri cutaneous actinomycosis.
abstract: Actinomyces meyeri cutaneous actinomycosis is a very rare disease. It often results from contiguous dissemination of an underlying focus. We report a case of pulmonary actinomicosis with secondary cutaneous involvement which led to the diagnosis. A 51-year-old man presented with an indurated, erythematous plaque on his right chest wall. He had been diagnosed with pneumoniae one month prior ago and received antibiotic treatment but symptoms persisted. Fibrobroncoscopy was normal and bronchoalveolar lavage samples were negative. The cutaneous plaque evolved with fistulization and drainage of serohematic material with white grains. Actinomyces meyeri was cultured from bacteriologic samples. Ceftriaxone and doxiciclin were administered for a total of 12 months with complete resolution of the clinical condition.
