Erysipelas, painful, erythematous and oedematous involvement of the periorbital skin and left cheek, extending to right periorbital region.
Erysipelas: Superficial bacterial skin infection usually caused by Streptococcus pyogenes (Group A); affects lymphatics. May be accompanied by fever, chills, nausea, vomiting, headache, and arthralgias. Physical:Warm, swollen, erythematous plaque with sharp border; face & legs. Investigations: Complete Blood Count (CBC) & Differential, blood and wound cultures, Erythrocyte Sedementation Rate (ESR),urinalysis. Differential Diagnoses: Cellulitis, contact dermatitis, herpes zoster.
Erysipelas, Streptococcal, left lower half of leg, there is brawny, erythematous oedema with tenderness.
Erysipelas of face: group A streptococcus Painful, well-defined, shiny, erythematous, oedematous plaques involving the central face of an otherwise healthy male. On palpation the skin is hot and tender.
Erysipelas of leg: Methicillin Sensitive Staphylococcus Aureus (MSSA), the lower leg is red, hot, tender, and edematous. Erythematous plaque is well defined (blue mark). The infection is recurrent with interdigital tinea pedis as the portal of entry.
Erysipelas, hot, painful erythematous patches, accompanied by fever and malaise, typically caused by a streptococcus. Erysipelas can affect the face and in this case the border against healthy skin is very distinct and raised: the (STEP SIGN).
Erysipelas, on the leg one observes extensive wide patches identical with those on the face but having a less accentuated margin. A mixed infection is found in most cases (Gram +ve and/or Gram -ve bacteria). There is often a portal of entry for the bacteria e.g. a lesion between the toes or a wound caused by trauma.
Erysipelas, of the leg with bulla formation.
The two gram-positive cocci, Staphylococcus aureus and the group A beta-hemolytic streptococci, account for the majority of skin and soft tissue infections. The streptococci are secondary invaders of traumatic skin lesions and cause impetigo, erysipelas, cellulitis, and lymphangitis. S. aureus invades skin and causes impetigo, folliculitis, cellulitis, and furuncles. Elaboration of toxins by S. aureus causes the lesions of bullous impetigo and staphylococcal scalded skin syndrome.
