Actinotignum schaalii Pilonidal Sinus: Case Report and Review of A. schaalii Soft Tissue Infections

A. schaallii has been recently recognised as an emerging uropathogen but its role in skin and soft tissue infections is less well-characterised. We describe an unusual case of A. schaallii pilonidal sinus infection and review the literature for skin and soft tissue infections involving this organism. A. schaallii soft tissue infections tend to involve the groin, breast or perineum and are sensitive to penicillins but are usually resistant to metronidazole, clotrimoxizole and ciprofloxacin.
