superficial kind of cellulitis | erysipelas |
bacteria causes almost all types of cellulitis | streptococcus |
pain out of proportion to how lesion looks | necrotizing soft tissue infections (NSTI) |
type of superficial cellulitis, almost always group A strep; sharp, raised borders | erysipelas |
type of intertrigo caused by C. minutissium | erythrasma |

etiologic agents of impetigo | A B-hemolytic streptococcus pyogenes or S. aureus |
predisposing factors for impetigo | truama (minor), underlying dermatoses, poor hygiene, previous antibiotic therapy, warm temps/high humidity |
appearance of impetigo non-bullous | small pustules or vesicles that erode crust (honey-colored), surrounding skin is usually inflammed |
appearance of impetigo bullous | vesicles or bullae containing clear or turbid fluid, surrounding skin can be normal |

dermal ulceration, crust is yellowish-gray and thicker and harder than crust in impetigo, children and elderly at risk | ecthyma |
pyoderma etiology is almost always | S. aureus |
localized, walled off collection of pus, can develop at any cutaneous site, starts as firm nodule that becomes fluctuant | abscess |
deep-seated erythematous nodule, common in hair bearing regions or areas of friction, develop central necrotic plug | furuncle |
large area of coalescing abscesses or furuncles | carbuncle |
gold standard treatment of abscesses, furuncles, and carbuncles | incision and drainage |

adjunctive therapy to I and D | systemic antibiotics and warm compresses |
populations at risk for CA-MRSA | native americans, african americans, homeless, populations in close quarters, incarcerated military recruits, children in daycare, competitive athletes |

predisposing factors for soft tissue infections | trauma, surgery, mucosal infection, underlying dermatoses, immunologic deficiency |
extends into subcutaneous tissue, borders are often indistinct, | cellulitis |
etiologic agents of cellulitis | GAS, S. aureau |
superficial cellulitis, raised borders with clear demarcation from uninvolved skin. | erysipelas |
etiologic agents responsible for erysipelas | GAS, very rarely S. aureus |
part of the body that is most commonly affected by erysipelas | lower extremity and face |
treatment therapy for cellulitis and erysipelas | penicillinase-resistant synthetic penicillins or cephalosporins. use macrolides ( but not erythromycin) in penicillin allergic patients |
supportive treatment for cellulitis and erysipelas | rest, elevation, warm compresses |

most common etiology of acute lymphangitis | group A streptococcis, less commonly S. aureus |
gram negative bacteria found in marine animals that inhabit warm bodies of water | vibrio spp |
very rare in the US, usually acquired via contact with infected animals or their products or from feed, soil contaminated with spores of the bacillus | cutaneous anthrax |
systemic tx for erythrasma | doxycycline, macrolides |
