necrotizing fasciitis

fasciitis /fas·ci·itis/ (fas-e-i´tis) inflammation of a fascia.

eosinophilic fasciitis  inflammation of fasciae of the limbs, with eosinophilia, edema, and swelling, often after strenuous exercise.

necrotizing fasciitis  a gas-forming, fulminating, necrotic infection of the superficial and deep fascia, resulting in thrombosis of the subcutaneous vessels and gangrene of the underlying tissues. It is usually caused by multiple pathogens and is frequently associated with diabetes mellitus.

nodular fasciitis  a benign, reactive proliferation of fibroblasts in the subcutaneous tissues, commonly affecting the deep fascia, usually in young adults.

proliferative fasciitis  a benign reactive proliferation of fibroblasts in subcutaneous tissues, resembling nodular fasciitis but characterized also by basophilic giant cells and occurrence in the skeletal muscles in older adults.

pseudosarcomatous fasciitis  nodular f.

fasciitis [fas″e-i´tis]

inflammation of a fascia.

necrotizing fasciitis a fulminating group A streptococcal infection beginning with severe or extensive cellulitis that spreads to involve the superficial and deep fascia, producing thrombosis of the subcutaneous vessels and gangrene of the underlying tissues. A cutaneous lesion usually serves as a portal of entry for the infection, but sometimes no such lesion is found.

nodular fasciitis (proliferative fasciitis) a benign, reactive proliferation of fibroblasts in the subcutaneous tissues and commonly associated with the deep fascia.

pseudosarcomatous fasciitis a benign soft tissue tumor occurring subcutaneously and sometimes arising from deep muscle and fascia.

necrotizing fasciitis

Necrotizing subcutaneous infection Infectious disease A rapidly progressive bacterial infection that spreads along fascial planes which, absent effective therapy–eg, debridement, results in skin breakdown with bleb and bulla formation, small vessel thrombosis and 2º necrosis, leading to subcutaneous anesthesia Agents Streptococci, gram-negative and mixed bacteria
