title: Pilonidal Abscess Associated With Primary Actinomycosis.
abstract: Pilonidal disease in the sacrococcygeal region usually presents as abscesses, recurrent inflammation, cellulitis or fistula tracks. However, few reports on actinomycosis affecting pilonidal sinuses have been published. We report a case of a 25-year-old woman who presented with a pilonidal abscess who underwent surgical drainage and debridement. Pus from the pilonidal abscess was sent for microbiology, which grew actinomyces turicensis associated with prevotella bivia and peptostreptococci. She was treated with oral amoxicillin-clavulanate after surgical drainage for one week and recovered well. Actinomycosis associated with pilonidal abscesses, though uncommon, should be recognized and can be satisfactorily treated with a combination of surgical drainage and antibiotics.
