8 CELLULITIS

9 CELLULITIS  CLINICAL MANIFESTATIONS:  -affected areas of the skin/underlying  subcutaneous tissues  -erythematous, tender, warm,  edematous.  -fever 

11 CELLULITIS  -s/s are caused by the bacteria, and the  body’s attempts to stop the infection.  -skin appears pitted, like an orange peel.  -area of redness spreads and small red  spots appear  -vesicles may form and burst

12 CELLULITIS -nearby lymph nodes may become enlarged and tender. (lymphadenitis) -nearby lymph nodes may become enlarged and tender. (lymphadenitis) -edema secondary to the infected area occludes the lymphatic vessels in the skin. -edema secondary to the infected area occludes the lymphatic vessels in the skin. -most patients only feel mildly ill, -most patients only feel mildly ill, - but some have fever, chills, headache, - but some have fever, chills, headache, tachycardia, confusion, hypotension. tachycardia, confusion, hypotension.

13 ERYSIPELAS  A specific acute, inflammatory disease  -caused by a beta- hemolytic streptococci  -characterized by hot, red, edematous  and sharply defined eruptions
