- anaerobic c. infection with subcutaneous soft tissues with any of a variety of anaerobic bacteria, usually a mixed culture including Bacteroides species, anaerobic cocci, and clostridia.
- dissecting c. SYN: perifolliculitis abscedens et suffodiens.
- eosinophilic c. recurrent c. followed by brawny edematous skin lesions or sometimes urticarial papular, annular, or gyrate lesions; affected skin and subcutis are heavily infiltrated by eosinophils and histiocytes, with scattered small necrotic foci (flame figures); of varied etiology; sometimes follows an arthropod bite. SYN: Wells syndrome.
- gangrenous c. infection of soft tissue with organisms that produce extensive tissue necrosis and local vascular occlusions; streptococci, clostridia, and anaerobes are known causes, but most cases recently have been polymicrobial. SYN: necrotizing c..

an infection of the deep dermis of the skin by b-haemolytic streptococci. It is most common on the lower legs and there may be associated lymphangitis and lymphadenitis. It is otherwise similar to erysipelas, but the margins are less clearly defined because the infection is deeper. Penicillin is the antibiotic of choice for treatment.

cel·lu·li·tis (sel″u-liґtis) [cellule + -itis] an acute, diffuse, spreading, edematous, suppurative inflammation of the deep subcutaneous tissues and sometimes muscle, sometimes with abscess formation. It is usually caused by infection of a wound, burn, or other cutaneous lesion by bacteria, especially group A streptococci and Staphylococcus aureus, but it may also occur in immunocompromised hosts or following erysipelas (q.v.).Medical dictionary. 2011.
