ABSTRACT
We present the case of an actinomycotic mycetoma of the foot due to Actinomycetes viscosus. It evolved for nine years on the foot of a 26-year-old patient from a rural environment: Douar Inezgane (city in southern Morocco). Bacteriological study of the skin and grains confirmed the diagnosis. It showed positive bacilli on direct examination and on Gram staining and in positive culture. Histological study showed a polymorphous granulomatous inflammation without signs of malignancy with actinomycotic grains. Then we retained the diagnosis of primary cutaneous actinomycosis without visceral locations. The treatment was based on antibiotics: penicillin G by intravenous infusion for five weeks, relayed orally by amoxicillin associated with trimethoprim-sulfamethoxazole for long periods. After six months of treatment, we observed a favorable outcome with reduction of the swelling, nodules, lymphadenopathy, fistula's number and extension of time of issue of grains. The current follow up is 15 months. The primary cutaneous actinomycosis is still relevant in Morocco.
