A subcutaneous abscess is an abscess located in the "hypoderm" or subcutaneous tissue. The abscess is formed due to a hypodermal infection by a bacterium, a fungus or a parasite. Typically, this kind of abscess needs drainage, usually for a minimum of 24 hours, by means of gauze packing or a Penrose drain.
