title: Perianal abscess caused by Propionibacterium avidum in a cirrhotic patient.
abstract: We describe the first case of community-acquired Propionibacterium avidum subcutaneous tissue infection in a cirrhotic patient. A 70-year-old Chinese male with a 2-year history of hepatitis B virus-induced chronic liver failure and hemorrhoidectomy 17 months previously presented with a painful left buttock abscess, which was culture positive for P. avidum. Being a normal flora of skin with low pathogenicity, there have been only 3 case reports on P. avidum infection, all associated with surgical intervention within 2 to 6 weeks before the onset of P. avidum infection. We hereby review the literature on P. avidum summarizing
