title: Botryomycosis: improved therapy for a difficult infection.
abstract: Botryomycosis is a chronic bacterial granulomatous disease often involving the skin and subcutaneous tissue. Head and neck involvement is rare. Botryomycosis presents with clinical and histological features similar to actinomycosis or mycetoma, but the causative organism is usually Staphylococcus aureus. Microscopically the organisms appear to be encapsulated in granules, which are thought to protect them from the effects of standard courses of antibiotics. Botryomycosis usually requires surgical intervention for cure. Major debilitating surgery has been required for most patients, because the infection has been unresponsive to seemingly appropriate medical therapy. We present an 8-month-old male with periorbital botryomycosis. Surgical specimens for diagnosis were obtained, but complete resection would have created debilitating functional and cosmetic defects. The lesion failed to respond to nafcillin alone or combination therapy with hyperbaric oxygen, but showed slow, steady improvement with long-term clindamycin. The patient has been disease free for more than 4 years, with minimal scarring and no functional impairment. Prolonged medical therapy for botryomycosis may be a viable alternative to the traditionally recommended surgical resection, thereby reducing cosmetic and functional morbidity.
