SCLEROSING OSTEOMYELITIS AND ACTINOMYCES-NAESLUNDII INFECTION OF SURROUNDING TISSUES

We present the case of a young man with chronic Actinomyces naeslundii infection in the lower leg who underwent a below-the-knee amputation after unsuccessful attempts at diagnosing and eradicating the infection, Actinomycetic organisms from environmental sources can engender a dense fibrotic tissue response without fistulae, Such a response led to a painful, sclerosing, nonsuppurative infection of the bone and surrounding tissues in our patient. This clinical picture, at least the bony and periosteal reaction, was compatible with Garre's osteomyelitis.
