-day history of fever and an area of swelling and redness on her right
forearm. Six hours ago, she noticed red streaks extending from her forearm
to her elbow. She has not traveled, and there is no history of trauma. Her
temperature is 37.8°C (100°F). Epitrochlear lymph nodes are enlarged.
Examination of the distal radial aspect of the right upper extremity shows
an 8 x 13-cm warm, erythematous area of edema that is tender to palpation;
there is a warm, tender red streak extending from this area to the elbow.
Which of the following is the most likely causal organism?
A) Haemophilus influenzae
B) β-Hemolytic streptococcus
C) Pseudomonas aeruginosa
D) Salmonella choleraesuis

lymphangitis. if erysipelas, the question would tell you the "clear borders"

I think I know why you r asking. yes, strep can cause both cellulitis and
erysipelas.
