Cutaneous actinomycosis: a rare case.

ABSTRACT

Cutaneous actinomycosis is a rare presentation. Here we present a case of cutaneous actinomycosis with no history of trauma or systemic dissemination. The isolate was identified as Actinomyces viscosus by standard methods. The isolate was found to be penicillin resistant by Kirby Bauer disc diffusion method. Therefore, the patient was treated with cotrimoxazole and improved. Thus, this case highlights the importance of isolation and susceptibility testing in actinomycotic infection. The sinuses have healed, and the patient has recovered.
