Actinomycosis is a chronic and suppurative infection caused by an endogenous Gram-positive bacterium. The usual sites of infection are the head and neck, thorax, and abdomen. Primary cutaneous actinomycosis is very rare and usually associated with external trauma and local ischemia. We report on the case of a primary cutaneous actinomycosis of the nasolabial fold in a 70-year-old woman. The patient had a well-defined subcutaneous nodule on the nasolabial fold without any other lesion. The patient was treated successfully with surgical resection and combined antibiotic therapy. There has been no recurrence during the 3 months period of follow-up.
