Unilateral erythema and skin induration and calor. Erythema with increased edema. Ulcer is healed, only granulation tissue.

Based on the diffuse erythema of the entire, the fact that it’s circumferential instead of just over the anterior portion of the shin like we see with acute venous stasis dermatitis (see this case for an example) I diagnosed her with cellulitis. She has had a history of sepsis due to other bacterial infection and she has had multiple hospitalizations in the past. Therefore she is at risk for MRSA as the cause of cellulitis. However, because of recent clindamycin use and risk for clostridium difficile I will start with cephalexin and monitor her progress with a 24 and 48 hour recheck. She was encouraged to start using her compression stockings again and increase her exercise.

Diagnosis: cellulitis.
Treatment: cephalexin.
Outcome: unknown.
