Pinna Perichondritis Complicated by Necrotizing Fasciitis

Necrotizing fasciitis is a potentially lethal infectious process usually found in the abdomen, perineum or extremities. In the head and neck it is rare to occur and usually starts from a dental infection but can be initiated from any source. Pinna perichondritis is not uncommon. However, progression to necrotizing fasciitis is not a usual complication. Typically, necrotizing fasciitis is caused by group A Streptococcus, Clostridium perfringens, or a mixture of aerobic and anaerobic organisms while methicillin-resistant Staphylococcus aureus is an uncommon causative agent in monomicrobial infection. We described a case of a 57-year-old gentlemen with diabetes mellitus sustained polytrauma in a motor vehicle accident, which later developed pinna perichondritis and necrotizing fasciitis caused by methicillin-resistant Staphylococcus aureus.
