Various hospital-acquired infections following soft-tissue trauma may lead to cellulitis. It is unusual to have infection occur in areas around surgical wounds less than 24 hours postoperatively, but if there is such a clinical problem, group A beta-hemolytic Streptococcus [GABHS] or Clostridium perfringens (which produces gas that may be appreciated as crepitus on examination) is the usually cause. Acinetobacter baumannii is an emerging multidrug-resistant pathogen in these scenarios. [33]

Cellulitis due to lymphatic obstruction or venectomy may be caused by non–group A streptococci (ie, groups B, C, and G). [22, 23] Postvenectomy status following saphenous vein stripping can also result in cellulitis. [22] Cellulitis may also be associated with tinea pedis, and in such cases, culture of toe-web spaces may help identify a bacterial pathogen. [34] Lymphadenectomy following tumor excision, such as mastectomy, is also a predisposing factor for cellulitis.
