Primäre kutane Aktinomykose am Gesicht

Primary cutaneous actinomycosis is only occasionally diagnosed. We observed a 51 year old male patient with a slowly growing, at presentation 1,5 × 2,0 cm measuring, strictly cutaneous-subcutaneous tumor at the left cheek. After diagnostic tissue biopsy we treated the tumor by complete excision and consequent antibiosis with penicillin G for 4 weeks. Since there was no involvement of further soft tissues or bones of the face we diagnosed a primary cutaneous actinomycosis.
